Lantern LED cree xm l t6. Review flashlight UltraFire E17 LED CREE XM-L T6

Hello, I continue to get acquainted with Chinese flashlight building and I hasten to share my modest knowledge with the public.
During the sale period in the Aurabuy store, I purchased a flashlight with a head mount. The model for sale in the photographs looked beautiful and practical, as its design demonstrated the possibility of freeing hands from holding the lantern. In addition, it was reported about the huge brightness of the glow (2000 lumens) and an extended package was offered. The purchase promised to be successful. Now the cost of the flashlight is $25.34 (which indicates that the sale really took place :).

Package
The packaging of parcels in this store is approached with responsibility, the “pimples” are not spared, the cardboard box is strengthened with adhesive tape, a trifle - but nice.
Lantern Packing:
Thick cardboard box, with a glossy finish, clear inscriptions and colorful illustrations. Her size:

Inside the box there is a form of foam rubber, in which "parking" places for the contents are neatly cut out.

The packaging is just lovely, I didn’t even raise my hand to throw it away.

Appearance
Assembled:






Dimensions: length - 9.5 cm, width (with head) - 7 cm, head diameter - 3 cm, battery compartment diameter - 3 cm.
Weight (with battery) - 205 gr

Disassembled





The body of the flashlight is metal, the mount is soft rubber, the lens is plastic.









The build quality of everything is very good. The threads on the joints are even, there is lubrication. The on/off button works well.


The head of the lantern rotates smoothly. The elastic bands are elastic and elastic, they do not cling to the hair, moreover, they are regulated according to the volume of the head. The paint is applied neatly and evenly. The blue color is also present on the inside of the lantern head, creating a small blue halo at the beginning of the beam.
Diode is like this:

On the head:




The head is quite comfortable, the elastic bands do not press, the weight of the flashlight is practically not felt.
The direction of the light beam and its width can be adjusted.

Glow example:
Next to my other flashlight (XML-T6 with a declared brightness of 900 lumens, powered by 2 * 18650)


Someone obviously does not finish, or there is no 2000 lumens, or there are more than 900 lumens :).
The flashlight consumes battery energy - economically (batteries have not been used yet), heats up, with prolonged use - moderately.
Other accessories:
battery cylinder

battery container

Bicycle holder

Purpose:
In general, a flashlight is needed in order to see something in the darkness.
The reviewed model can be mounted on the head or, for example, screwed onto the handlebars of a bicycle. The handlebar mount will still limit the field of view, so I plan to use it on my head. In this case, the flashlight will be on the same side as the eyes, and will be able to unmistakably illuminate the place where they look.
I am already looking forward to the onset of the warm season, when, having put this wonderful lantern on my head, I can ride a bicycle at night.

Conclusion:
Beautiful, bright and comfortable flashlight.
I have only positive impressions after checking its performance. To do this, illuminating my path with my forehead, I walked along the dark streets. Now I can say with confidence: the flashlight illuminates the earth at night - it's great and I could be seen from afar.
In my humble opinion, this flashlight is a great purchase.

Waterproof hand lamp on CREE XM-L2 viki710 writing in July 3, 2015

Super Bright 100M Underwater 1800 Lumens CREE XML T6 LED Diving Flashlight/Torch - Black - $20.31
The product was received in the online store chinabuye.com for a review for free.


For several years, quite a lot of different Chinese lanterns have been flashed through my hands - large and small, manual, head and camping. Ordering this flashlight is a consequence of my desire to have a universal flashlight for most occasions. To do this, it was necessary that the lantern:

- was water resistant enough to withstand heavy rain and being dropped into the water,
- conveniently turned on with the thumb,
- wasn't very big
- Worked on 18650 cells.

The selected flashlight model is widely available on various trading platforms, but everywhere it is positioned as a noneme. On the other hand, it is clear that it has some kind of brand prototype, but I could not determine which one.

As for the characteristics of the flashlight according to the information of the store:

Light flow: 1800 lumens,
Light-emitting diode: CREE XM-L T6,
Body material: aluminum,
Certificates: CE,FCC
Operating modes: High/Middle/Low,
Water resistance: up to 100 meters.

The flashlight came in a standard OEM store packaging - a cardboard box with a bubble wrap. Spartan delivery set - the lantern itself and a lanyard to it.


Lantern length - 15 cm.


Weight - 209 g.


Turning on the flashlight is done with a slider, not a button. In this case, the brightness of the LED depends on the position of the slider.


The slider is magnetic. This allows you to adjust the brightness without touching the contacts directly. The freedom of the slider is limited by a metal retaining ring.


Adjustment with the slider on the one hand is convenient, as it allows you to smoothly adjust the brightness, but on the other hand, due to the small size of the handle, the slider is under the thumb, and you can accidentally turn on the flashlight. The problem would be solved by fixing the slider in the off position, but unfortunately, it is not provided.

Feels like the lantern seemed even a little small to me. If you keep your thumb on the switch, then the palm is longer than the handle - and this is with my not very large hand.


Structurally, the lantern consists of three main parts - the head, the handle and the back, which are assembled using threaded connections. For water tightness, each connection is shielded with two silicone rings.


The flashlight is powered by a single 18650 battery.

It is wiser to change batteries by unscrewing the back. To make it convenient, it has special grooves. Inside - as expected, a negative contact in the form of a brass spring.


Lantern head. The lens is glass.


Between the retaining ring and the lens is an additional silicone ring for water resistance.


In the description of the store, the flashlight LED is declared as CREE XM-L T6. But the CREE XM-L T6 LED does not look like this (see picture). In the offers of similar lights on the trading floors, there is a mention that the LED is CREE XM-L2.

Visually, CREE XM-L2 differs from CREE XM-L T6 in the presence of two legs instead of three and a key on the board (shown by arrows). It also looks like the LED of this lamp. Thus, the flashlight is still on the CREE XM-L2 LED. The description is inaccurate.


In accordance with the CREE XM-L2 specification, it produces 1052 lumens at maximum power (10W), which means that the claimed luminous flux for this flashlight of 1800 lumens is too high.

Lantern lanyard has a rubber insert and is quite long - 30 cm.


This design allows you to conveniently mount the flashlight on your hand.

Lantern testing

The lantern gives a rather diffused light. In principle, this is not surprising, because it is positioned as an underwater one. And under water, the range is not particularly useful.

Below is a beamshot at maximum brightness. Light spot diameter - 190 cm. Distance from the wall - 120 cm.


Changing the brightness of the lantern with the slider, in my opinion, is best illustrated with a video:

As for the range - here is a photo at night under conditions of diffused city lighting:


As you can see, the reflector setting also allows you to shine quite far into the distance.

And finally, the waterproof test. I don’t dive, so I don’t plan to swim with a flashlight, but situations are different, and no one is safe from falling into the water. As you can see from the photo, everything is in order with the waterproofness of the flashlight.

conclusions

In my opinion, the lamp is quite successful. Among the advantages, I would note the following:

- small lamp size
- Conveniently located thumb switch
- stepless brightness adjustment,
- diffused light allows you to illuminate a large area in front of you,
- high water resistance.

Of the shortcomings - the switch slider is not fixed in the off position. Those. so as not to inadvertently turn on the flashlight, you need to follow the slider. There are also some inaccuracies in the declared characteristics of the lantern, but the Chinese constantly sin with this, and they are not critical.

Looking through various reviews on Muska, including reviews of flashlights, I caught myself thinking that I don’t have a single flashlight at home. Or rather, what is, a flashlight can only be called conditionally. Based on this, I decided to order a couple of inexpensive flashlights for myself, this is a review of the first of them.
In short, it could be better.

Often you need a small flashlight, which is needed in order to highlight something during work, or, for example, calmly walk to the elevator if a light bulb burns out on the site.
Based on this, I looked after myself a small flashlight, moreover, immediately with a battery in the kit, in vain.
By the way, when ordering, the price for it was more, 8.87 bucks, apparently not only I got it.

But let's start, as always, with what came.
As always, a yellow envelope, pimply.

The lantern itself is in a cardboard box, also wrapped in thin pimply polyethylene.
The part with the button was not screwed in, the battery was inserted the other way around. When I saw it, I thought, well, that's it, they burned it, I was wrong.

Actually, the flashlight itself looks very neat, there are no complaints about this part at all, a normal coating, no scratches, etc. My wife liked it very much, small, convenient to carry in a purse.

There is a button on the back, a single-mode flashlight, a button with a light accumulator, but very weak.

When turned on, I was surprised at the rather high brightness and the fact that it does not heat up. It became curious what was inside, dismantled. Zoom flashlight, LED module screwed to the part where the battery is inserted. There is lubrication (I also managed to get smeared). On the back of the supposedly driver board there is an inscription CX-410D, in fact this inscription does not mean anything.
There is no driver in the flashlight. The current from a freshly charged battery is 1.2 Amperes and changes as the voltage changes, the higher the voltage, the greater the current. With a linear driver, the current would not change, with PWM it should have decreased. There are thoughts to put at least a current-limiting resistor. Standard driver boards most likely will not fit, since I saw the smallest one with a diameter of 17mm, in this flashlight a board with a diameter of 15mm.
The board is pressed into the holder, the contact is the copper itself of the board, when the front of the lamp rotates, it can scroll and rub, it is quite possible that the copper will quickly rub off.

Addition. The driver is present, PWM, with a hole in the chip.

The LED is very similar to CREE, but I won’t vouch, maybe it really is Cree.
There are several sealing rubber bands, two on the front aluminum part with a lens (I struggled while unscrewing it, in the end I had to take pliers) and one on the back.
The processing of metal parts is neat, there is nothing to complain about.
There is a metal spring ring on the LED module, when sliding the front part to adjust the zoom, it helps to fix it a little from self-shifting. But the front end walks with a pretty decent backlash.

Close up photo of the diode.

The weight of the flashlight without battery is 43 grams.

With a complete battery 61 grams.

Without much hope for the best, I measured the battery capacity during charging, set the charge current to 140mA (about 0.2C from previous 14500 batteries), stopped charging when it reached 4.2 Volts and the current dropped to about 10% of the initially set charge current.
Got 382mAh. With the fact that the capacity was measured when charging, I think that it is really about 320-330.

Well, a photo of how the flashlight looks in the hand. I'm generally right-handed, but it's inconvenient to take pictures with my left hand.


Summary.

Pros.
Everything looks pretty neat, feels good in the hand.
Delivery is fast and accurate, no issues.
It shines very brightly for its dimensions, if at night it shines under your feet, it is enough with a margin, if you put the zoom on the narrowest beam, then it illuminated the balcony of the ninth floor without any problems.

Minuses.
There is no driver, and therefore no current limit, 1.2 Amperes at 3.5-3.7 Volts is about 4 watts. That's a lot for such a small flashlight. What prevented the installation of a simple current stabilizer is not clear. Addition, the driver was, but apparently failed on the way, as the battery was inserted the other way around.
There is absolutely no battery, with the declared 1200 mAh it has only 320-300. Given the lack of a driver and a current consumption of 1200mA, this looks a bit wild.
Taking into account the first two points, the flashlight's operating time is approximately 10-15 minutes maximum, if you put a more powerful and high-quality battery, then the LED will most likely overheat and die. In general, you can’t use it with your own, and you won’t put a good one.
There is play when adjusting the beam width.
From time to time, contact disappears during adjustment.

In general, the picture is very sad. With all its pleasant and neat appearance, as well as high brightness, the flashlight is of little use for operation, rather even unsuitable. I'm upset, we must take the convoy.
This item was provided free of charge for review by chinabuye.

I hope my review was at least somewhat helpful. At least people will know what not to buy.

Along the way, the question of who knows what kind of microcircuit can be used there, write, please, I think it makes sense to try to replace it.

A detailed analysis of the board showed that the driver was presumably in the Step-Up topology, i.e. raising. This means that initially the flashlight was made to run on a conventional AA battery, they decided to sell it with a lithium battery, which, as you know, has a higher voltage, in addition, they managed to reverse it. It makes sense to repair this driver only if you plan to use it with a 1.2 Volt battery or battery. Will not work with lithium batteries.

The product is provided free of charge for review by Chinabuye.com
Such a useful thing as a headlamp is indispensable for cyclists, athletes, fishermen, in addition, it is very useful in everyday life - both at home and in the country or in the garage. This review is about one of these lamps.

The reviewed flashlight uses a bright CREE XM-L T6 LED, and also has a non-standard place for attaching the on/off button for such devices - not on the flashlight body itself, but on the side, on the head circumference elastic band.

The packaging is unremarkable - a simple cardboard box without any printing and indicating the nature of the contents

Scope of delivery: flashlight, charger and adapter for euro socket

Charging is rated at 4.5 volts at 500 mA

The whole design consists of four elements - the flashlight itself, adjustable elastic straps for attaching to the head, a power / mode switch button and a battery compartment located on the back of the head.

The button is located on the left side and it is installed "in the gap" of the power wire going from the lamp to the battery pack.
Pressing the button is soft and clear. The button sequentially switches the following modes: bright -> dim -> blinking-> off.
There is no memory function for the last mode, so when you turn on the flashlight immediately goes into "bright" mode

Behind, i.e. on the back of the head, there is a compartment for batteries

The lantern itself turned out to be fixed with a special clip, so if necessary it can be removed

The direction of the flashlight can be adjusted in steps from horizontal to vertical

The flashlight has a "zoom" function, i.e. increasing the range of the light beam using an optical lens. In the normal mode, designed for close-up illumination, the lens is pushed as far back as possible.

To narrow the light beam and, as a result, increase its range, it is necessary to pull the lens forward

Behind, under the plastic grille, the metal body of the lamp is visible

The battery compartment is a plastic box with a rubber lid. The lid tightly closes the compartment and is attached to the body with a special ring to prevent loss.
The batteries can be either one or two 18650 batteries (not included, so you need to purchase separately).

You can charge the batteries right there without removing them from the compartment. To do this, under a special rubber plug there is a corresponding connector

Unremarkable at first glance, an insert made of soft white plastic with the inscription "LED HEADLIGHT" when turned on turns out to be nothing more than a rear signal light. Depending on the mode of operation of the flashlight, it will glow (or flash) in red.

Now I bring some beam shots

No zoom (maximum brightness)

Price: $5,83

Today I want to present a review of another CREE XM-L T6 zoomable LED flashlight.

Product Description:

100% brand new and high quality
Model: YM-217-T6
Black color
LED: CREE T6
Material: space aluminum alloy
Switch: at the end
Battery: 1 * 18650 or 3 * AAA batteries
Continuous light: 2-4 hours (depending on battery)
Size: 13.7 (length) * 3.5 (head diameter)
Brightness: 2000 lumens, effective range 200 meters
Circuit: Constant current driver, DC-DC.
Driver: 5 modes (3 brightness modes, strobe and SOS signal)

The description also contains a phrase that when the battery voltage becomes low, the driver will raise the voltage, that is, it will work in Step-Up mode.

As for space aluminum alloy, they certainly turned it down. Apparently they meant aircraft-grade aluminum. I do not know how it differs from ordinary aluminum. In short, the case is aluminum, there are sealing rubber bands, the threads are long. Such a case will protect from splashes and rain, of this I am sure.

The flashlight is noticeably larger than the ones I had before.

The silkscreen on the head of the lantern is printed obliquely.

Bronze clamping ring, which should improve heat dissipation (this is unlikely, since this ring does not touch the LED board itself, but rests against soldering) and protects the Covex lens from heat (this may be so).

We disassemble the flashlight. To unscrew the bronze ring, you have to use tweezers with sharp ends.

Under the ring is a dielectric gasket. Includes insulating tube and container for three AAA elements. It also includes a Li-Ion 18650 battery perfectly. Everything is standard.

Driver 5-mode: 3 brightness levels, strobe and SOS signal. I don't need a strobe and SOS. Over time, I will change this driver, I saw information on how to do it.

As much as I hoped that the heat sink would be normal, my hopes were not justified. There is a hole under the LED board and the board itself touches the module in which the LED and the driver are fixed with a very small surface. Thermal paste, of course, no. LED on long wires, in general, the heat sink module is very long, oh, there would be a normal platform for contact with the LED board ...

But we have what we have. All I can do for now is to smear the contact points of the module and the LED board with thermal paste. Then you will either have to replace the entire module, or at least lay a copper “penny” under the LED board.

Large LED. Indeed CREE XM-L T6.

Specification for CREE XM-L T6.

The flashlight is noticeably larger than its counterparts from previous reviews. Here are reviews on and flashlights.

It can be seen that the zoomed flashlights shine in a uniform circle, which has a clear border. Illumination within the circle is almost uniform. This is why I love flashlights with a lens.

The third flashlight has an elongated reflector and gives a bright narrow beam of light and a wide area with low light.

When zooming (narrowing the beam of light), two left flashlights give a bright square - a projection of the LED crystal (the camera overexposed this square, in fact, the structure of the crystal is visible).

The second flashlight in this mode still has a brighter ring of light. This makes itself felt by the silver ring holding the Covex lens, it reflects part of the light. This is not very good, but not that important, because. in this mode, the flashlight is unlikely to be used. It is not visible in the photo, the camera could not convey this, but the larger (left) flashlight has a much brighter spot of light.

If we compare two zoomable flashlights, it can be seen that the hero of this review, in the widest exposure mode, illuminates a much larger area at the same brightness, compared to a smaller flashlight.
