I hope I don’t need a dehumidifier. I just spent all my money on LEDs.

Can you give us any hints or teasers?

We Weak? How so? It’s 480w of LM301B and well documented. Plenty of info available on coverage and efficiency. I’d rather build my own light, but I don’t think this one is weak.

Well, I jumped on a four pack of 3000k qb120v2 when they came back in stock this morning. I’ll get those running and then add some reds and uv when I can. Woohoo!

I like it! Can I run six or seven of the $10 Cree strips with one or two strips with 730nm all on the same driver?

I like the idea of adding multiple spectrums to my light, on separate drivers. Are vesta strips still considered a good choice? Sol-strips? Any suggestions?

I just don’t want to buy a kill a watt for each driver and it’s a hassle moving it from driver to driver. I’m cheap and lazy.

The lights I linked to come complete with drivers and heatsinks.

Nice work! I pay more in winter than Summer, but I think it’s been about $0.13 per kWh lately. I’ll let it ride for now and add a 220 circuit sometime when it’s convenient. I’ll do it to be efficient, not to make it pay.

Here’s a solid option. This is the kit, it’s very easy to assemble, no soldering required. You can also buy it assembled https://horticulturelightinggroup.com/collections/kits/products/320w-xl-qb-v2-led-kit

I haven’t tried this light, but it looks promising. @bcblondes is on the forum and is a RIU advertising supporter https://www.bcblondes.com/product-p/bcb-340-301b.htm

Doh!

I suppose I could. It might cost $100 to run a new circuit and change cords. How long would it take to make up the initial cost in energy savings? Any mathematicians in the house?

Yeah, the indoor horticulture scene musta been pretty rough 60 years ago. I mean, good luck finding a hydro shop! But, ok, I’ll try to be happy with 91%, for now.

Boooo I want my 30 watts back.

But 10%? Is that normal? What happened to 93% efficient?

Huh. I assumed that yours flashed also. Weird.

where did my 30 watts go? 316 watts at the wall, 287 watts out the driver Who’s got my 30 watts!?

A 630 watt CMH might be worth considering

I hooked mine up. It didn’t blow up. The watts display works, voltage shows 99.99 What I don’t like is that every time I power it up the lcd backlight flashes on and off, drives me crazy. If I hit the button three times it will stop flashing, but I have to do that every time it turns on. Boooooo
