Id take a very hard pass on all of those. Its blurple, amazon and no real dets on any of the chips nor wattage (1200w is not the actual draw) = the trinity of no go.Hey guys just want an opinion on this light as in thinking of getting it?
You're likely going to buy the light and it'll grow a marginal little plant and you'll get sick of the awful purple light and stop growing. When you're ready to start growing, throw that light away and get something better. Most of the ebay and amazon chinese lights are just toys HLG is good.Hey guys just want an opinion on this light as in thinking of getting it?
I already have a 600w LED one but fancied a bigger one for when I go up in size on the tent, thanks for the input though I shall scrap that idea and look at quantum boards.Id take a very hard pass on all of those.

Look up quantum boards here on the forum instead, i think theyre on Amazon aswell.
Nice one mate, wanted as a replacement when I upsize, shall stay away and check out the quantum boards as rocket soul suggested above, thank you for the inputYou're likely going to buy the light and it'll grow a marginal little plant and you'll get sick of the awful purple light and stop growing.

Try diyleduk.com mate, you only need a 135w Quantum board if its for your 2x2 tent.I already have a 600w LED one but fancied a bigger one for when I go up in size on the tent, thanks for the input though I shall scrap that idea and look at quantum boards.
You can also build your own light if thats your fancy, a fair bit cheaper and not as hard as youd think. Stick to quality diodes: samsung lm561c or lm301b, or bridgelux eb gen 2.Nice one mate, wanted as a replacement when I upsize, shall stay away and check out the quantum boards as rocket soul suggested above, thank you for the input

Will it fit in the loft? You can get loft tents if not.Il give it a look now mate going to go for a 120x120x200cm
The loft is only a temporary thing I'm renovating a shed at the bottom of the garden for the bigger grows, just got to get insulation boards and run power down there and that's readyWill it fit in the loft? You can get loft tents if not.
Either way you want around 30w per square foot with them type of LEDs
2 plants in a 1.5x 1.5 , I imagine you mean feet, in which case yes its plenty.His prices are fair. He also does his own builds called scope.
I'm looking into LED light for my 1.5x1.5 tent and I this seem like a good purchase. I was wondering if it would be enough to cover the area with 2 plans in it?
It so hard to figure and choose the best one
The 135w kit is good for a 2x2 foot space but it does crank up to about 150w so would be enough for a 3x2 if you add a couple of cfl, although I would add a couple of screw in LEDs rather than cfl personally.I recently bought a 135w 4000k V2QB from HLG ,....I plan to grow in a 3x2x6.5' (2 plants) cab I built, I'm hoping this light is going to be enough for the 1st grow....thought of using cfl's as side lighting...never too much light right ( ?), but what spectrum makes sense to use as this is for veg and flower.....it was suggested that the 4000k would be OK for both....any thoughts?
Found this on the net - https://www.waveformlighting.com/horticulture/convert-lux-to-ppfd-online-calculator
EB2 has 80 CRI which is considered as low? According to this guide - https://www.flexfireleds.com/color-rendering-index-cri-and-led-lighting-what-is-cri/,,,
"- Lights with a CRI that is measured greater than 80 are considered to be more than acceptable for most applications.
- Lights with a CRI that is measured greater than 90 is generally considered “High CRI” lights.".
So,,,, if i load 40000 lux and "low cri led 3500k" in the calculator in the first link i'll get 641.48 umol/s/m2.
But if i take 641,48*71 i get 45545?
A couple of questions if your going the strip route. What means are you going to use to waterproof the strips between each shelve?@coreywebster I have to agree. Lawmakers must know something we don't lol with this plant count stuff I wish it wasn't a limit! So let's say we can dream a bit you know and I was trying to light a 5x10x9 space I figured getting 1.5gpw with 5 elbows takes 1500 watts but how many strips will I need to increase efficiency high enough while maximizing low wattage. Most ppl run their strips at 75% so if I leaned towards 40-50% I would have to buy more strips but idk the math formula for ratio between percent to run each strip at to determine sweet spot for high ppfd : low wattage.. do you know any helpful members you could tag or point me to for help?? Thanks my man cheers
