Okay, so a 50E achieves 7.25A and gets 1135 lumens at 30 seconds. Now if using a 40T at 8A I get the same lumens. Djozz told me that 7A should be the limit and it looks like he’s correct by the numbers I’m seeing
I’m not seeing any improvement over the 1mm version
Turns out I damaged the led at the beginning when I shorted a wire on the reflector turning purple.
New led at 7A gets 1300 lumens. Increasing to 8A only gets 13 lumen gain. I’ll be driving these with a 50E in Convoy’s ramping driver for 7A
Yes, but the SST-20 DR has a very low forward voltage which you need to use a special driver. If you use this driver it’ll burn through most of the battery voltage very quickly to run more efficiently at a lower voltage.
If it’s actually an 8A buck driver the excess voltage is not wasted. However, a true 8A buck driver will require a very large inductor and probably be quite expensive compared to most Convoy drivers so I wonder if something is lost in translation here…
A few things landed and tested from Convoy, all really excellent thanks Simon!
L21A XHP35 HI 4000k : Really nice quality. Light is strong and pleasant.
S2+ with W2 Green : This is so much fun, it gets hot on high Great power to weight ratio. Decent throw and spill.
Upgrades for C8: LH351D 5000k and OP Reflector. Such an awesome upgrade for my C8. Sliced the dome and it has decent throw, really nice color, noticeably warmer than 5000k, really awesome all rounder now!
