I just bought another 240w kingbrite unit. I honestly wouldn't waste watts or money on all that cree, uv and ir stuff.. lm301b/h LEDs put out more light per watt than any of those. IR and UV leds are notoriously over priced, under powered and last less than half the time of normal LEDs.

I just stick with the 3000k straight up. No red, uv, it or cree BS. Just a waste of money and watts. If you want to supplement your spectrum, use other bulbs/tubes to do it. They are cheaper, they last longer, they put out way more light, and when they burn out, you just replace a 20 or 30 dollar bulb/tube, not the entire fixture.

IMO every watt not spent on lm301 LEDs is a watt wasted, at almost 2 times the light output of other LEDs.

Just the way I look at it. The amount other stuff those ir uv and red LEDs add is almost nothing. You're paying a lot more for them, they dont last as long and they are eating up wattage that is better spent on more light.

I first originally was gonna buy ones off eBay kevlin range I'm sure that's like the one your explaining to me lm301b

Then I seen others.in my link above from Chinna i assumed they where the same but it said version 2, so I though light be better and added reds all sounded good says aides flower

But thinking of it my 600wtt hps is just white light.

I think I heard of king brite. Do u have a link I'll have a look thanks, or have I already linked it myself sounds familiar lol

Since adding red supplimentals to my other sets I have seen a positive change, but that’s always subjective. I’m with you on everything else the IR and UV is useless. I ran over a year with no reds and trying a number of
Mixed spectrums by mixing boards. So far my best results have included, but these reds that I posted are in fact not the same as the Samsung strips I posted about previously. Nor are they the mix, but I paid even less than what’s advertised and I couldn’t find a better deal at the time. I am currently running over 25 quantum boards, some haven’t been turned off except for major power losses in over a year. @BigCube is dead on the money, if you are not running lm301’s your wasting money

Understanding light.

Just a short disclaimer here, I am not an expert. I've done my own research, I will show my sources and I am willing to be corrected. I will try my hardest to keep my bias out of the equation as best I can. Light a small portion of the electromagnetic radiation spectrum...

will these be flower only or both? that would be my deciding factor

For flower but be nice to be able to veg as well I'm thinking 3000-3500 can't decide about to buy any minute now lol

BigCube said:

If you're in a tent, a deciding factor may be; more blue light will give you taller plants.

Now if you're talking 3000k to 3500k. I dont think you would see much of a difference. 3000k would tend to be a tiny bit shorter and bushier.

Mr.jiujitsu said:

mine is NOT king bright, but another manufacturer. I justlike the 4 panel single power supply with 5mm heat sink. Any of thequantum boards will do you just fine. Just find the best price point and remember the grass is always greener on the other side

BigCube said:

The heatsink is 10mm. Extruded aluminum fins.View attachment 925615

You could stand on it.

including fans is 10mm? How thick is the unfinned portion? 3mm and 7mm fins? I sold all my previous 288 boards that had the same styl heatsinks. Thank you

I'll break out my calipers....

About 3 mm with 7 mm fins.
Its solid. I wasn't kidding when I said you could stand on it
