Hey guys, I need your feedback.
I'm designing a new board for "Fonarik" flashlight that I mentioned here
I have multiple ideas at this point:
1) use same leds on both sides -one with flood lens and one with narrow
2) use different tint/temperature on dif sides
3) use second side for RGB leds so color can be chosen
4) use second side for UV, RED, Green light

Any thoughts will be appreciated
