Very nice review. Thank you! What kind of tint shift did you get after dedoming?

DBSAR · February 7, 2018, 6:14am

Nice test!

Warmer (approx 5000 - 5500 K CCT) tint with a bit green in it. But much less than of Cree LEDs (XP-G2 / XM-L2), so it should be okay. Better color tint you might get if you slice the dome.

Wow, almost 100% improvement of cd by dedoming

Nice, thanks.

Thanks for the testing

Thanks for the test. With the low Vf and high luminance dedomed this LED is the optimal one (IMO) for single cell triple emitter applications. The emitters are driven very well without the risk of blowing the bond wires. With an aspire 4300mAh 26650 my convoy L2 triple SST40 pulls 19A.

I built a triple that pulls just over 24A with these (multiple cells in parallel though). It’s a fun light but I’m not very fond of the tint.

At that brightness you could could use a filter and it would still be very bright.

Nice review!
I achieved 160 kcd in an Emisar D1S with dedomed SST40. Nothing else changed just the led.
Same led in an Eagle eye X6 with fet driver: 88,5 kcd
Same led and fet driver in Convoy C8 AR coated lens: 136,3 kcd with dome: 70,5 kcd
Convoy L2 Fet driver with dome on: 172 kcd

Can anyone suggest a good 17mm to 22mm 1s-2s buck drivers to run this LED up to 7-8A, or so?

Nicolicous · February 15, 2018, 9:45am

hey ZozzV6

how did you dedomed SST40?

X31 · February 15, 2018, 9:50am

I’m curious too, I put one with dome in my D1 so I want to try in my D1S too

ZozzV6 · February 15, 2018, 2:26pm

It was an early led that somebbody told here on blf it was easier to dedome. I putted it in regular 95 octane petrol floating on wires upside down. And the dome falallen off. It leleft a little on the phosphor but I removed it with an Xacto knife under microscope.

Nicolicous · February 19, 2018, 12:46pm

1 more question

how long did u leave it in 95 octane petrol ?
