Well, they do beat CXB3590 in terms of efficacy. I guess I will research that diodes for a couple of days, first results showing that they are cheaper than COB's, more energy efficient and it takes roughly 4300 pcs. of LM561C SPMWHT541ML5XAU0S6 to replace a single 1000 W HPS or 12 overdrived COB's with active cooling. The price of 4300 LM561C SPMWHT541ML5XAU0S6 is very good and I can buy 4300 pcs. for the same price as for the 4 pcs. of Cree CXB3590 3500K CD bin. It saves the money that I can spend otherwise, building a clone room for instance.
But connection of that LED tapes still bogging my mind. Need to visit LED Gardener, heh.
What about light penetration? It's good thing to have in the setup, since manifolds aren't always perfect, isn't it?
Yeah, I get that. Bought a laser thermometer for that exact purpose.
Active cooling COB's is easy because they are well suited for mounting in square vent channels, LM561C on the other hand can be tricky since they are going to be well distributed throughout the grow room. It's possible to mount them into the square vent channels like COB's but there are complications.
And speaking about LM561C - they come in tape, so are they pre-soldered toghether or what? I don't like the idea of manually soldering ~9000 connections, not at all. Inb4 I can't use SolStrips.
I will seriously consider buying LM561C instead of Cree COB's. Need more research.
And sorry for the long post, I was silenced for 24 hours for being newbie
