Driver for SSC P7 LEDs

[martzak]

So far about 10 dives on it, deepest one to 175ft, still bone-dry.

It looks great. What is the canister? Did it start out as a diver's canister, or did you adapt something for that use?

 

[martzak]

I can send you a BOM if you want.

 

[martzak]

Yeah, it's just a otterbox8000.

I thought I'd go out on a limb and give this a try:

DealExtreme: $81.00 Diving Cree SSC-P7-C-SXO 3-Mode 900-Lumen LED Flashlight Kit (2*18650/4*CR123A/4*16340)

It should arrive in a week and I'll be testing it to 100 ft. If it works I think an attachment could be made for the back of the barrel to convert it to a Can Light with 6 x 18650 kind of like the Dive Rite 700.

Any concerns from looking at it?

Diving Cree SSC-P7-C-SXO 3-Mode 900-Lumen LED Flashlight Kit
Brand: Diving
Model: -
Emitter Brand/Type: Cree
Emitter BIN: SSC-P7-C-SXO
Color BIN: White

both marked don't go together - SSC P7 mean Seul SemiConductors and it is big competition of Cree ))

Emitter BIN: SSC-P7-C-SXO

if this light my provide top 700 lm not 900 like they say because of binning LED SSC-P7-C-SXO .....C bin go to 700lm max . to the 900lm go D bin and up to 1100lm go U-bin for final sum add 96% max efficiency of the reflector

There are at least 2 versions of this light. One using a Cree MC-E and another using a SSC P7.

From what I understand the driver does not put out 2.8 amps of current so the light will be under driven.
If you wanted to convert it to a can light here is waht I would do.

1.Remove barrel section ( it looks like tail cap may thread direct into head.
2. Change driver.
3. Put gland in tail cap and build a cannister that allows you to disconnect the battery as the light head switch will not reliably turn off. ( dont want it turning on by accident)

Improvements.
1. change the LED for a better Bin
2. Use a Maglite based light head instead. Its cheaper and better IMHO.

I wasn't aware that they didn't change the driver from the MC-E version. I think alot of the specifics contradict themselves because the P7 is a new version and it looks like they copied most of the MC-E page. If I could get an actual 500-600 Lumens I think I would be happy with it.

I just got the light in today. It does appear under driven so I'll be ordering a new one of those.
It doesn't have a very tight hotspot either. Can anyone help explain how to fix this?
