Finally finishing the CXB3590 build....watch and enjoy

Are the lenses better than reflectors, or is it a matter or application? I was just looking at the F13838 reflector, which looks to have a pretty nice spread.

Nice job. I'm building a 36"x36"
15 cob set up as soon as Jerry gets back with a quote. Got my heat sinks and mean well 240's
I'm following along man !

This one is for a friend. Super soft run 3x3 - 9 CXB3590s @ 700ma.

I'll be putting 50 CXB3590s in a 5*10 @ 1050ma. That will be the one to watch :)

Should have my veg lights done today or tomorrow. Will keep it updated as I progress though.

I'll tell you about the shootout between two of my modules, identical in every way except one has 80 degree lenses and the other is bare; lenses are killin it.
I've read that lenses degrade light output by like 3% ish but it seems to me that not using them might also degrade output because of increased light dispersion. Seems lenses would focus the light better than without thus making up for a small output loss? Do you use reflectors with your lenses?

Your doing vertical though right @ttystikk ?

Would love to compare rigs when I finish off my bloom room. 5*10 but hanging from the ceiling.

Are you using 36v or 72v? And what Kelvin rating?
CXB3590 3500K CD bin 72V, 700ma, the Meanwell HLG-185H-C700B driver gives each of 4 COBs 54W with the dimming wires capped. Each module pulls at total of 224W from the wall, anywhere between 110V-277V. I planned for 824 PPfD across the whole array.

I'm totally down to compare n contrast, because you're running a slightly different setup and getting more PPfD than me?

Open or closed spaces? I'm wondering if the lenses are more beneficial in an open environment than a small closed one like a tent as light will be absorbed one way or another and while you cannot increase light output with lenses, you can focus intensity so all of the light is where you want it.

These walls aren't covered in reflective material just yet. That could make a difference.

In theory I think the lenses make no difference in a small closed space, but in a situation where any light that doesn't initially hit the canopy is lost I think lenses would make a huge difference. It'd be worth testing. I may have to build a new light with lenses to find out.
