       @azonenberg What do you use it for? Resin cure?

       @dtl @azonenberg huh, my LEDs at least according to their datasheet should emit a spectrum pretty much centered on 370nm, that shouldn't make much of a differnce. Need to work on better extraction of chlorophyll, it seems.What I use my UV source for: excite little plastic phosphorescent seal figurines, tbh. (and also: prototype for multispectral honey analysis)

       @funkylab @dtl How big an LED? My 365nm source is a Thorlabs diode source rated at close to 1 watt of optical output power so it's *bright*

       @azonenberg @dtl PLCC 2835. Haha, nowhere 1 W Popt, this is safe without protective eyewear.Xinglight XL-2835UVA-02. (and I found ny mistake – these are 390nm, not 370 nm)

       @funkylab @dtl also "plcc 2835" sounds like a terrifying j-lead package the size of my dining room table

       @azonenberg @dtl "close to toy safety" was actually more important than any other optical spec on this.

       @azonenberg Well we've never met and you might just be really really tiny?

       @funkylab lol.Ok let's see, 1.27mm pin pitch and 2835 pins is 3.6 meter perimeter, divide by 4 for a square package and...  It would actually "only" be 90cm on a side give or take a bit
