There is a led which was tested side by side with a 1k hid where the only variable was the light and it performed neck to neck with it. Its a blackdog led, the $2000 model

I have a high quality 600w LED(685 true watts) and I treat it just like a 1000w hps as far as hanging distance/intensity and coverage... and I got similar results. But cooling is way less. Between the 40% in lighting and the 75% in cooling, it is saving a good amount.

they look nice but depending on strain, not comparable to hid size wise imo.

right see, and that's just nucking futs imo. 2k?

I just harvested a HP from 4 plants using 2 blackstar 240w panels and 1 blackstar ion 8 panel. They are decent panels def not the best LEDs out there but able to pull 2-4 oz per plant easily. You guys all trashing blackstars must have tried the old ones I think they have made improvements. And t5s are great for veg. I also use my t5 for side lighting and switch to 2700k bulbs and have other t5s lights surrounding my plants for side lighting with the LEDs above. And the ion 8 is a monster LED from blackstar its all 6w and 10w chips with 4 10w cree chips :)

.5 grams per watt. Super job for LED. You are a good grower indeed.

Now lets double that and we have a break even with HPS watt for watt. We all know that a gram per watt is very doable with HPS.

Question is, other than not changing bulbs and perhaps a little less heat what would justify the high cost of LED? Especially when newer LED tech is always just around the bend. It's a fun technology for use on small scale for sure. I can't deny the appeal. I sure wouldn't want to double my utility bill or half my yields to use LED.

they aren't really 240w that's the LED wattage I think they pull around 130w and I am still learning next grow I am trying hydroponics and much much much bigger pots. Went from 2.5gal pots to 10 gal fabric pots and my plants are huge :P

You think? Seriously I'm interested in what they really pull.

Maybe 240w total but they prob use a ton on the fans or some shit these panels aren't super powerful compaired to the ion8.

EDIT: I FOUND THIS REVIEW ON AMAZON

These 240W Blackstars work great for indoor growing and this version is meant for mostly flowering but works for vegging too. The 240W is the number of diodes times the wattage, not the actual wattage that it pulls. It does pull roughly 133 watts with around 10 watts or so being from fans. Even if you calculate 120w of actual light these are still the cheapest LED light per watt on the market (besides the extremely cheap chinese junk). I have 6 of these in a 4x4 tent. It might be a little overkill but I don't have a lack of light. I also have a couple of the vegetation versions that work great. Compared to ISIS, Spectra, Magnum, etc. Blackstar is a great bang for the buck.





That was the older model I think the newer one the LEDs are driven harder maybe 150w or slightly more.

"Maybe" isn't better than "I think"

You have a meter? Not saying your way off but there's no point in meaningless numbers from a guesstimation.

I really want to know if I can grow using half the wattage. It would be a game changer.

No meter unfortunately I wish I could take a reading I wonder if anyone else with the blackstar v2.0 240w panel has some testing equipment and can get us some readings.

Thats a cool looking setup! Which LEDs are you using and what was price?

When do you remove your fan leaves? All at once during flowering? if so which week of flowering?


Sorry bout all the questions... just still have a lot to learn about LEDs and figure might as well ask the growers who are getting actual results.

What is the height from the floor that you hang the lights? 2 feet from canopy light the 1000w?

the older blackstar 240's pull right @ 130W i believe. It's been a while and my memory is fuzzy.

It's the apache at600. The last run was over a 4x4, it was my first I keep it it at 30" and had the tighter lenses on it. This round I have the wider ones on, and keep it at 24". I am getting matching par numbers all across my canopy to the 1000w hps I have no the other side of the divider this run. Check my sig for the whole grow, I youtube the whole thing. And also the current grow which is a side by side with hps.

If that's what can be done with a 1kW HPS then I must be way behind the curve. Lol

Never said it was record breaker of grows...just comparable. You guys asked and I provided...don't see anyone else stepping up too much. Low yielding strain and some other issues...all in the thread, but not horrible, 503g. I could give excuses but I have figure out how to really judge it. Now I am running blue dream in a side by side with a 1K(I think you stopped by actually) and they are divide light wise, yet in the same environment and we will see if it was the light, or me that was holding things back.

I will check it out thanks.

I just showed you the blackberry and it didn't meet your standards. But check out my current run, might be better for you.

with t5's i got buds the size of milk cartons with aquarium bulbs and fresh water bulbs. I got 24 oz off my last t5 grow wit 2 t5 8 bulbs. the most i ever got off 1000 was 19 zips. my first induction grow i got a pound. but much smaller plants and not enough plants to fill the space. im on my 2nd inductin grow now.

watts do not mean a thing. just like lumens don't mean a thing. Not all watts are the same its about eficacy , cri, par, and efficency. 1000w is 20%-30% efficient. so its creating at most 300 watts of usable light and 700 watts of heat (wasted energy).

with quality led and induction. its about 500- 600 watts to match the yield and coverage of a 1000w. now a 1000w of led will cover twice the area and match 2 1000w hps's

with cmh. 2 330w cmh's outperformed a 1000w hps and covered more area. those have higher par than a 600w hps and the highest cri of any bulb., the higher the cri the more even spectral distribution. the cmh i had, has a cri 93, my induction cri 90, my led cri 80. hps cri around 25-35. Imo cri is more important than efficiency and par. they go hand n hand.

the reason hps have such poor cri and horrible spectrum is due to them using aluminum arcs. Cmh use ceramic arcs. which distribute spectral light more evenly and degrade less and last 3 times longer than hps.


here is another myth all the hid guys buy into.. mh during veg and hps during flower. You actually want the same spectrum in veg and flower. Maybe with some added 660nm deep red in flower. The sun never changes its spectrum year round. plants have been growing under the sun for millions of years. Most outdoor done right is better quality than any hps grow.

I have to agree with you about changing lights between veg and flowering. one study showed that the change in solar spectrum between mid summer and mid fall only resulted in a 4% increase in deep red. the study was done in new york and closer to the equator where plants are actually grown the change is even less. a greater shift occurs between morning and noon on any given day. like leds induction lights are interesting but expensive.it seems good results could be achieved with mosy lights using the proper strain and growing technices.I also like the results I am seeing with T5 aquarium lights.
