Led Users Unite!

[THT]

alright, i know nothing about LED's, only what the watt's/true watt's mean. i'm running a viparspectra 300w right now for 5 plants, i'm looking to get another LED light between $60-$90, as i'm in flower now. I know with LED lights, no matter what you're getting what you pay for. if anyone needs more details, let me know.

You take a Watt meter and plug in your LED. This gives you the actual wattage draw at the wall.
Its not ever what the company markets it as. a '300w' china led is gonna get you maybe 125-150 at the wall if you are lucky.

More details about what? The Vipar 300's? Please, no..! NO! Please, not..
Same as above... Add some quantumboards! There are different versions available that siuts your needs.
QB65, QB100, QB120, QB288 v1 +v2.
You could get a 4pack QB65's for ~79 or 89$ I believe.

details about my grow space or something maybe? i'm in a 4x2 grow tent, i'd be lucky if i could fit one QB lol

How tall is the space?

All you need is 250-300w of led to flower in that space.

4-5ft

4-5ft

Are you very good with building things? Maybe do a little wiring. You could build a nice strip light for around $100-$150 that could work around that vipar.

For a 2x 4' area only 2 QB288 are needed.
They are on sale currently!
You could get a kit with 2 quantumboard288 v2's and a slate2 double heatsink for 188$

https://horticulturelightinggroup.com/collections/all/products/qb288-with-slate-2-double-combo?variant=8673715388508

The only other thing you need is a Meanwell HLG-240H-54A driver(60-65$, from mousser). That means ~250$ for one of the most efficient 250w growlight, that last you at least 5-7 years.

i don't plan on growing for 5-7 years, i'll be over it by the end of this year. I don't want to spend more then what i produce, ya know. i've put in $200+ on this already, although all of this is for personal use, i dont wanna be in the hole too much.

i'm not unfortunately.

Yepp, one quantumboard in the center and the two other along the sides. A ready to use QB288 kit is only 187,50$ and you could add another one later and finally get rid of the shitty ol' blurples.

Nearly impossible if you invest in a quality light. With only one QB288 at 150w you could yield 200-225g easily and a complete kit is only 187,50$ and the real quantumboards have a high value retention and get used good prices.

i understand that to you 187 isn't alot, but i'm on a bit of a tight budget atm. If I had the money to drop on it, i would, but i dont.

Then wait a while. With your current light 1g/w should be possible and it could last for a while.
In the time you save what is missing or give something away from what the 5 girls deliver.

Another way would be a growlight mod/hack! Interchanging the built-in LED's against a 4 efficient Citizen1212 COB's. But that requieres some DIY work too.
The smaller Quantumboards(65, 100 and 120) are also available on am4zon and you could use a cheap chinese 100-150w LED driver with 24v output(15-20$). As mentioned above, the smaller boards are a lot cheaper, a 4pack QB65 is only ~80$ or so and they need no heatsink.
Only plug the ± wires from the driver into the sockets on the boards, plug the power cord in and it works!
No heatsinks, no fans, absolutely silent and passively cooled!
And 4 QB65 can work with up-to 150w(37,5w per board). For a small space like yours they offer a perfect light spread and you could still use the old lights if you want. With QB's 1,5g/w and more are possible.

so 150 true watts, right?

i was looking at T5 lights 4x8 8 bulb 50 ea watt bulbs
along with my led

 

[whoajoey]

LIGHTTECH 4 x 8 set up using 8 T5 6500K bulbs inc 2 - 900 wt leds
or
HPS 1000 inc 2 - 900wt leds
trying to get this going your help is appreciated

build your own DIY quantum setup. like this whole thread is about. all in one 900W leds are most likely gonna be a 150W draw from the wall...

 

[Purpsmagurps]

If your heat is an issue, go QB and ditch the ac.

 

[Purpsmagurps]

if you need heat, use the HPS combined with ac

 

[Moflow]

Yeah, T5 is a lot easier than the old T8/T12 standard.
This ballast should work and wiring is a breeze.

But, mate, why use the shitty Arcadias when you can get HTG's PureUV tubes? They cost less than the Arcadias and lasts much longer.
Yeah, they are a lot more powerful and yes, they can harm the plants in the wrong hands, but that's actually a good thing!! It means, they can hung much higher and cover almost triple as much area and produce still usefull amounts of UVB.
You get 440μW/cm² at 1' height and 170μW/cm² at 2' from 2 and 4' PureUV bulbs,
my Arcadia(12%) delivers only 150-180μW at 1'!
For my next run I would like to try it with a little more, 250-300μW, and a PureUV could hung ~18" above the canopy to deliver that intensity. That means one PureUV tube covers at least 24x 36" canopy surface. The Arcadia must hung 8" above the canopy to get the same 250-300μW readings. No need to mention that you would need 2 or 3 bulbs to cover the same surface area.
Also a 1000h old PureUV still put's out more UVB like a new reptile tube. One could use them for another 1000h in his veg area or simple reduce the distance to increase UVB and still get the desired intensity numbers.
If I could get them here where I life, I would already own them!

With luck, @Aolelon will send me six 24w tubes this week. Keep your fingers crossed that shipping will not be so damn expensive ...

Yea a saw those HTGs but was thinking of my lights at 10" - 12" above the canopy and was thinking they were a tad too powerful.
Obviously the HTC Tubes aren't for sale in eu uk

How pricey for shipping depends on how it's done I suppose, is the package coming from the US? It was around £20 for the gg boards.
Have you an SPD chart on the htg PureUV tube?
