End of next week I hope, still need to fine tune firmware and add some stuff.

MZ 5700K 90CRI will be available in ~2weeks.

You'll need orange peel reflector for C8 to get smoother beam.

F.i.l.a.s · August 18, 2018, 11:49am

Sure, I already prepared the HOST, new C8+ Sand color, SS bezel with orange peel reflector.

led4power · August 18, 2018, 2:37pm

Does C8+ have same iner head dimensions as C8?

Now that you mentioned it, which OP reflector do you have?

I have few from old C8 and they are 31.5mm high, SMO reflector in newer C8 is 32-32.5mm high.

Is there 32-32.5mm OP reflector for Convoy C8?

Wtb x6 spacers. Hurry up guys

Kiribaru C8 head arriving today

F.i.l.a.s · August 19, 2018, 9:04am

I measured,

orig. C8 smooth refl. 32,7mm
some C8 Smooth 31,5mm
Fasttech C8 orange peel 32,9mm
Banggood C8 orange peel 32,8mm

I installed OP refl. to C8+ without any problem. It seems fit will be fine. You only need smaller gasket, because a reflector openning hole is smaller.

These gaskets from FT fits fine.

Thank you for reflector details, just ordered 2x OP on Banggood.

I'm not worried about reflector compatibility between C8 vs. C8+, but I'm not sure C8 spacer for 6x ANNA optics will be compatible with C8+.

I would buy several spacers for Manta Ray C8.2 if available.

led4power · August 20, 2018, 5:59am

For several pieces you should contact BLF member Kiriba-ru.

F.i.l.a.s · August 20, 2018, 7:14am

I recommnend you send a message to Simon on Aliexpress shop. He knows the best if there are some minor changes of inner dimensions.

The_Driver1 · August 21, 2018, 5:27pm

What kind of jst connector are you using exactly? What is it’s maximum width ignoring any notches on the side (can be sanded off)?

I need to know what diameter hole in the (C8TT) head is needed to fit it through as I assume that you will offer preassembled drivers with wires.

led4power · August 21, 2018, 6:24pm

JST SH connector. You need 5.5mm or better 6mm hole.

led4power:

Shorts specs:

*0.7mOhm FET, bottom pcb and fet drain is soldered directly to brass case, this eliminates additional contact resistances (those can be higher than FET resistance itself) which are present in classical PCB-retainer tailcap

*ultra-capacitor as auxiliary supply - practically unlimited life,reliable,fast charge, no need to replace it unlike coin batteries

*0-600uA Constant current channel for illumination LEDs

*Press-button momentary switch

*Configuration mode - adjustable illumination brightness, switch UI style, lockout, short-long time threshold set, factory reset.

Switch style 1 works like this: short click changes mode (short-long time threshold can be adjusted in config. mode,default is 0.4sec), long click turns flashlight off. From off, flashlight is turned on at switch press.

Switch style 2 works in the opposite way, short click is on-off, long click cycles through modes.

Entering into config. mode is done by holding switch from off for few sec and entering password after that, config. mode is very similar to LD-x4 config. mode, with table based menu/sub-menu.

For now I plan to have versions for Convoy S, M, C8 lights (with rubber tailcap), and EE X6 lights, also can be other lights which have compatible Convoy/X6 tailcap parts.

I can make custom versions for some other lights if there is enough interest.

Style 2 ui is gonna work great for me. This is amazing stuff. I’m definitely taking one so my shopping cart is parked for now on your site.

Got some 6x optics, problem with 7x ANNA is that central optics must be shorted by few mm by drilling or similar tools to make room for wires.

Also yesterday tried this C8 with DD on high option enabled, just to see what is max. practical output.

Luxmeter with CC @18A showed 380lux at start, with DD on high enabled output increased to 450lux at start, or about 6000lm OTF. Not bad for 90CRI.

This means max. current is about ~24-25A with VTC5A. Light heats up noticeably faster vs. CC @18A.

Wieselflinkpro · August 24, 2018, 11:05am

Hopefully I can mod your parts for Manta Ray C8.2.
I am waiting for some parts in your shop, such as Luxeon V 90CRI, C8 Spacer, possibly fitting Momentary Tailcap-Switch and so on.

When did you think, you will get the Luxeon V 90CRI?

led4power · August 24, 2018, 11:27am

You mean Luxeon MZ 90CRI? Luxeon V is still not released in 90CRI.

For now I will only have spacers and tailcaps for Convoy C8 and EE X6, next possible candidate is Sofirn C8F 21700 host.

Nicolicous · August 24, 2018, 12:00pm

we need this kit

Chatika_vas_Paus · August 27, 2018, 6:30am

It looks much better than with empty optics. Will it be available in your store?
And what will be the price for spacer for C8?

led4power · August 27, 2018, 7:50am

I will offer 6x ANNA within C8 DIY kits for now, I have limited number of them. Price of spacer is yet to be determined, I will have first batch this week.

Buoyen · August 30, 2018, 6:29pm

The LD-B4HV. Can someone tell me what the different connection points in this image are: Capture hosted at ImgBB — ImgBB

+ battery power is on the back side

battery power is on the edge (I)

A is + LED, B is - LED and C is gate?

This driver should turn on when connected to power (without switch) ?
