BLF ReyLight Titanium Flashlight 3*Nichia

[ReyLight]

==This is a group buy for Complete BLF ReyLight Titanium. Will start producing after 10 days or as long as there are 50 members in.

Sorry for the long time of silence after the GB of hosts. I'm always the most helpless guy here, asking for favor. Really appreciate your kindness and help. Many thanks to JohnnyMac,-the-,LSX,DB Custom, djozz, ChibiM,bibihang,Calmaja,Gunga and all the rest of you. (Kinda hard for a Chinese boy to remember those IDs.)

Been here for 3 years, learnt a lot of things, made several custom lights, and BLF ReyLight Ti is our very first light,which is designed by all of us. Due to my lack of experience, some problems happened and the lights cound not be assembled perfectly. But after some experiments and getting many suggestions and feedbacks from you, finally it's on the go.

Anway, enough of that.-----------------------------------

Here comes the light:

Specifications:

Material: Titanium

Length: 82/112mm Wo/W extension

Diameter: 25mm

Weight: 128.5g (with clip)

LED: 3*Nichia 219B 4500K

Optic: Carclo 10507

Lumens: Unknown (Depends on the battery)

The highest known output is 2750lm at 3 seconds, 1775lm after 30 seconds, by a 18650 30Q, modded by djozz. However, he is using 219C emitters, which have 10-20% more output than the 219B emitters we're using.

Warning: This light can get very hot, very quickly. If you are not familiar on how to safely operate a light like this, please take caution when purchasing and use a normal non-high drain 18650 cell. This will still provide excellent output of 700-1000lm but will be a much safer option.

Driver: 17mm BLF DD + theStar Firmware

Switch: Omten

Tritium vial options: Green - Ice Blue - Yellow - Orange - Red

(Please note: Not all tritium vial colours are always in stock)

Hi Rey, great that this assembled flashlight is ready to roll!

Hi Rey, great that this assembled flashlight is ready to roll!

For the output, you refer to my numbers, but you mention that in this light the 219B is used, while I used the 219C. I'm sure that the output will not be the same.

oh,I'm so sorry, did not notice that actually. Will correct it.

Edit: updated.

[raccoon]

Rey, you've been working on this flashlight for so long...

It's really looking good! ;)

[M4D_M4X]

a beautiful light indeed!

[Ormbett]

Too radiant for me, but very nice looking

If we get nine trits, can we pick the colors? How big are they in case we want to add them later?

Yes, you can choose the colors. Its 1.5*6mm.

Hi Rey,
I have built a couple of these lights in different orientations for myself and others. The titanium is not the best conductor of heat so on a hot build with a fet driver the guts can get very hot very quickly. If your selling on Kickstarter to non-flashaholics I would highly recommend using a driver with temperature regulation like the LD-2. This makes it much safer for normal people IMHO. Also I don’t worry about leaving it where my kids/wife can play with it.

Are all the issues with the host run being addressed? I’d love to have one of these, but at $160 it would have to be absolutely perfect.

Hi, Thanks for your kind advice. What LD-2? I know a Chinese supplier,provides LD-25,LD-29,etc. Are they the same LD?

With a normal 18650,it pulls about 3A, no biggie, and the firmware has a timer.

Yes,all sorted out. Button rattling, length,switch,water-proof ability problems.

I think that he means this one:

LD-2 : 6Amps pwm-less linear driver - info and FAQ thread

[image] LD-2 [image] Parasitic resistance of common drivers Important note! Driver comes with both solder jumpers unsoldered(driver's bottom side,1cell or 2 cell operation),so user must solder one of them (1S or 2S,never both at the same time) for proper operation. More under 2S (2x) Li-ion cell operation for “6V” LEDs" section.

With the higher Vf of the Nichia 219b the amps that this light pulls is not as high as my 219C build. There will be a heat issue anyway but not as 'clear and present' as in mine.

[Gunga]

Are the clip holes still drilled straight in or was that fixed?

Thanks.

@Gunga

ah, yes. Dont think it is fixable.

Edit:Because the bodies were already made.

[Bribo]

This driver is made for this light IMHO https://budgetlightforum.com/t/-/33706
I have made and tested this light with the LD-2 driver and xpl triples at 9A and 12A and 219C single at 6A with silicone cubes on the driver and the NTC resistor glued to the MCPCB. with this setup the lights throttle down as required to keep the led below 70 degrees C. I even wrapped one in a blanket and it went down to low and didn’t get too hot to touch.

Just updated my poor English to make the thread easier to understand.

Until now, no one in?
