McGizmo Sapphire ->4000K High CRI Seoul P4 mod (now 2 level + HA AA body)

[MWClint]

Bought the Sapphire with the intention of swapping in a seoul p4.
The plan is for around the neck carry.
My personal preference for my EDC's are either cool white SWO seoul tint or the 4000K seouls now..

This mod was tough, it took a few hours last night and all afternoon.
most of it was just grinding the Ti away.

led, small heatsink, circuit. will trim the heatsink down some..but it all fits
with some effort.

popped the lens out. this takes 5 hands.

The inside of the head has steps. the green is the bore i need the whole
head at so really, only the lip at the red dots needs to be ground away. the
blue is the lip at the base of the "reflector" area. the hole in the "reflector"
area is already big enough for the p4's dome. I did need to thin the step
behind the reflector to bring the seoul further up into the head.

slightly lowered circuit height. components are evenly topped out now. gives more space.

at 1.3v nimh the arc circuit was pushing 55mah to the seoul p4.
1.7v lith..was around 80mah. heatsink is usefull at this level.

bored out head using a dremel and a carbide cutting bit. took a long
time. majority of my morning was spent carefully grinding away.
Soldered some leads onto the led and dropped it in. forgot to take
pic of the heatsink, but it's just thrown in there with some thermal
grease. (heatsink is a small brass pill)

business end of the sapphire, seoul p4 with the glass back on

beamshot up close.. im using a dorcy aaa comparison so you can see the
difference in tints between the nichia and the seoul.

Some people just can´t leave their lights alone..... and that´s a good thing :wave:

I didn´t expect a Sapphire to be modded that soon, it´s a really good mod you did :thumbsup:

I ordered some cree XP-E Q2-5A emitters to make up a LE, being a smaller footprint (similar to the Rebels) I'm thinking I can avoid having to dremel the head.

Thank's for the inspiration!

Re: McGizmo Sapphire ->4000K High CRI Seoul P4 mod

Here's a beamshot comparison between the sapphire and an ex10 on low(also with a 4000K seoul)

i took ~20 pics until i got one that exactly represents the brightness and tint
of what my eyes see..both on fresh batteries.

this shot was about 6 feet away. the floody sapphire lights up the entire room
with a huge floody warm glow. very faint hotspot, not even noticable at 10+ feet.

Red is sapphire p4, blue is Ex10 p4 (both high cri s2 bin)

inside the red box is where the head was bored out.

Very cool mod!!!

That's a very cool, I mean warm mod!

Didn't expect the McGizmo Sappahite to be modded so quickly.

These three pictures are great! How much are you going to be charging to do these? I know the first time was really slow, but things are usually quicker next time, right?

Oh I'd buy one of these with a warm XP-E for sure.

It ought to cut the cost of the mod because the labor wouldn't be so intensive.
This would be about the perfect lanyard light for me.

Nice Mod :thumbsup:

What is current draw from a NiMh AAA? Must be insignificant if LED is only seeing 55mA.

Sweet! I'm not surprised to see a sapphire get modded so soon though. Good to see more people using more high cri emitters, they're pretty nice.

i have a pair of xp-e's (one warm and one cool)..when i originally opened the
package from digikey i was surpised by their tinyness. i'll have to measure,
but i do think they may work without having to bore the head. maybe
have to sand the square edges of the xpe's ceramic base...pretty easy stuff
compared to grinding Ti. xpe potted in glow powder epoxy would be pimp.

i wonder if Peter/arc would sell the driver pills alone for messing around with.
if it does work..they could make/sell xpe pills.

anyone have a spare pill from the "kit" version that they wouldnt mind selling?

using an xpe would allow a high power version.. plenty of extra space for heatsinking.

Bill

a fresh AAA is seeing 250mah at the tail(~76 mah to led) and seems to stabilize around 180mah(~55mah to led) after a couple minutes.
i have it in the AA arc body..and a AA eneloop is pretty constant at 250mah battery draw.

i'd say slightly over 4 hours of useful light on a nimh AAA.

Imagine the cash flow from selling XP-E pills that just drop right in!

Re: McGizmo Sapphire ->4000K High CRI Seoul P4 mod

we have some hipo driver options...

1. 500mah micropuck..135mah to led on nimh..500 on 10440.
2. 350mah micropuck...120mah to led on nimh, 350 on 10440.

i know these fit because ive stuffed a 350mah micropuck in a peak
matterhorn aaa driving a p4...sick little light. 2 hour runtime on nimh.
good balance between runtime and brightness. heat isnt a problem
driving the led at 120mah with a small heatsink.


ok, and I just ordered a 10.5mm mini flupic...i have a bunch of 10440's.
i'm pretty sure you can shave .5mm off that board...
:devil:

Mini-FLuPIC 10.5mm with program High>User Set Level>Low $25.00
Custom programmed 10.5mm mini-FLuPIC converter with the "Draco" program. High or burst is set around 450mA-600mA. The program is Hi/Burst>User Set>Low>LED OFF>Brightness set (for user set level) between 1-10 levels.

time to work on some heatsinks.
