I couldnāt resist and made another triple Optisolis S2+, this time in 4000K. My other 2 are 6500K and 5000K.
Same set-up as the others, host from Kaidomain, driver from Convoy, LED board from Adventure Sport Flashlights, spacer from Mountain Electronics, and Nichias from Virence.
Reflowing the Optisolis LEDs onto the board was very easy and they centered right up. I used a little more than usual soldering paste due to the big pads.
The driver needed a 470 ohm bleeder resister due to the lighted tailcap. I made a light purple tailcap by combining pink and warm white 0805 SMD LEDs. The driver retaining ring needed to be grinded down in the middle to make room for the 7135 chips.
And again I used a Carclo 10511 frosted narrow spot optic and frosted 1 side of the lens.
There are plenty of lumens, it has some throw, the beam is excellent, the tint is very good, and of course the CRI is amazing.
I also got a little creative with my Optisolis flashlights and matched the lighted tailcaps to the color of the hosts. And in case you are wondering, here are the measurements for the switches at 4.1 volts: blue = 0.15 milliamps (2.7 years), light orange = 0.33 milliamps (1.2 years), and light purple = 0.15 milliamps.
