I’ve got a FR rapid led puck and I figured the lens helps spread the light a bit better.
If you have a small area you could potentially remove it and focus it into a smaller area but you shouldn’t need a ton of uva,just run it longer periods

I’m using a 4x4 and a 2x2; the 2x2 i’ll leave it on, but i was curious if the lens had any filter factor (lumen loss from source) and/or if the led’s had a greater spread with the lens off.
Now the 13/11 light cycle is something I really wanna test after my first run with this thing on a different project.

I’ve got a apogee meter and a lux meter and neither pickup UV so I can’t give a for sure answer but I’m assuming yes there will be a small loss through the lens

I have not tried it without the lens. I actually use mine hour before lights on, to wake them up, and a hour on before lights off. I think it is better on the plants.
I have not done 13/11. I do 11/13 the last few weeks.

Your 100% correct. Why you see some multi band led with 540nm green

Huh??? How does that work, because we use green light during lights out…

@Syn yup I grew up thinking same think, but according to DR. Bruce Bugsby green light actually penetrates the leafs better then blue light producing more chlorophyll, chactk out his vids on youtube!

Here’s some light reading on how each specific wavelength effects each specific part of a plant/plants cells.
UVA/UVB are both useful for more than just producing trichomes and terpenes, they sanitize, killing mold and very tiny insects with radiation.
My OpticLED Slim 100 bloom booster has 365nm but I want closer to 315 for more radiation
Also for the lights out, plants don’t start any photosynthetic response until they’ve had light on em for like a steady hour, quick ins and outs or smoking sessions or whatever don’t cause hermies, steady light leaks do
