Dear xxxxx,

actually Cree makes most of them, whatever wavelengths they do not make are Epistar and Bridgelux, but most LEDs in Blackstars are Cree.

Not saying it's the truth, but at least it has been "verified" by gotham_products.

in my magnum I can see about 7 different colors including the UV you cannot see, cannot see 11 though ;)
Can you see 12 with GLH and 14 with Pro-grow?
I have tried to contact pro-grow for the past several weeks, by email - phone every day - contact form ...... nothing. They are on holiday or what? :D

I can see the 7 different on my old Pro-Grows and the 14 on my new one and could count 12 different on the GLH. That's odd about Hydro Hut I've usually been able to get what I want from them. Email has worked best they've always responded but sometimes it has taken over a week to get back with me (they probably got sick of answering all the questions I asked before I bought)

Bickering aside......This is still a great thread Wejuana.
Much to learn about these new lights.....Thanx for showing...

Its getting easier and easier to only pay attention to the Blackstar and the Hydragrow as Mike isn't selling the 290 any longer, so compare the cost of his 150's which are the old 180's powered at 50% ie., 150 watt (100 3 watt leds powered at 50% ). Awful expensive, just saying...

you would think that he would know the wavelength though...

Well, I'm there now.

And there's no mention of CREE anywhere that I can find. Could you post a link perhaps?

EDIT: No mention on Lighthouse Hydro's site either....

The bestselling LED on Ebay just got better. Redesigned for 2012, the BlackStar 240W UV is perfect for any size grow. Each unit covers 6 square feet (3'x2'). Use them in bulk for nice even coverage over larger areas. The BlacStar line has the best selling LED Grow Lights in the world for a reason - YOU CAN'T BEAT this combination of power and price! For this price you can gang them up and have a wonderful uniform grow and still get the peak PAR penetration that the 3 Watts chips deliver. This unit has 6 Bands (6 unique color wavelengths), and uses 3W LED diodes for the best possible light penetration.


Specifications:
- Size: 15.75" x 8.375"
- Coverage Area: 3' x 2' (6 Square Feet)
- LED Chipset: 3W
- Number of LED's: 80
- Rated Hours: 50,000
- Bands: 6 Band
- Red: 630, 660nm
- Blue: 425nm
- Infrared: 730nm
- Ultraviolet: 380nm
- White: 12000k
- Worldwide Voltage: 90v-240v
- Modular Power Cord (Available in US, UK, EU, AU)
- Warranty: 1 Year All Inclusive

Thanks all. I appreciate the info, knowledge, and even disagreements, but we just have to talk them out for the sake of learning.

You weigh in tomorrow right sleezy?!

What does your harvest have to do with CREE LED's? Never once have I questioned that Blackstar LED's perform, I'm using 2 right now for fuck sake. Click on the link in MY sig...

I'm just questioning the claim that they use 98% CREE LED's, Gotham says they do, but they've removed all mention of CREE from their ads and so has Lighthouse Hydro. I don't know if Blackstars are so much cheaper because they're using cheaper LED's (that still work amazingly mind you), or because they're selling units for a reasonable markup, not a ludicrous one like other LED companies.

I've read this claim in a few places;

Even if Lighthouse hydro bought 1000's of LED's they'd still be paying $2-3/LED and the cost of the LED would have to be higher. Therefore, they can't be using CREE LED's.


1000's of LED's? What about half million or a million at a time? Wal-mart will sign or cancel contract over fractions of cents. There's hundreds of LED's per panel, do people think they make 10-20 at a time??? lol

Yea imma say they need a lot more than thousands too lol. Even at 2-3 dollars an led ur lookin at 4 bills or ao probably as a wild ass guess for cost to build a 100 3w diode panel and that's about 400 bucks or so for about 150 wats if driven at fifty percent. That being said my 240 blackstar cost 250 so where's the 150$ price difference from? IMO Chinese labor and the fact the probably buy billions of chips for these things at a time especially if the claim that the same company is building all these LEDs in china. That would Beth's company sourcing the LEDs so not only Southey source blackstars LEDs say for example that they built advanced panels too I don't know if they do but let's use a hypothetical. They would have to order enough chips for specific manufacturers to fill both those companies needs I'm sure this is how blackstar gets their prices sole and mos of these other companies are greedy as hell. However there are some small ones like fake photoics LEDs for example they use cree but cost way more. They guy doesn't make as many panels so he doesn't get as many chips and he builds them himself not in china so they cost more. I get that it's too bad but he's a smaller company so it costs more but results are nice. So many things to consider u know

Spectra





Blackstar





Penetrator




So.. it looks like the Blackstar tent is feeling your negativity! lol.

In all seriousness though, this first run of LA Cons has had a few bumps with overferting the glh and penetrator tent a bit as well as the mag deficiency. I switched the fans to run only when lights were on for a period of about a week, and lets just say it threw stuff way off. I kept watering as I was previously, not really accounting for the pots drying slower.

In aiming to fix the GLH and Penetrator deficiency, the Blackstar is now showing signs of too much mag, by showing magnese def and have a feeling it is why the buds are slowing currently.

I think this is a good learning experience in the way that for the next set of plants, I will be watering using the same nutes as in this grow with the exception of needing to correct something on a per plant basis. I will be sure to note specifically if I am feeding a plant something different to correct an error.

This test will continue on, and everything is looking like its moving back in the right direction and leveling out.

All the buds are looking good themselves, some of the leaves just aren't at their prettiest.

what is it? I dont get how it would last so long, isnt it just regular bulb in there? has anyone ever tried those, what about the heat ? Thanks, still freakin expensive for a damn light, ... and 200$ shipping!! haha

Yes I've run one induction is plasma lighting albeit old style I ran one got frustrated with it because it wouldn't fire off in the morning via the timer. I had to manually start doin it after a week and his was unacceptable so I returned it. The good plasma systems are much more expensive but they work awesome plants like the light

As for heat the bulb itself way cooler than any cfl puts out a better par. The ballast part on mine got kinda hot but that's fairly normal for any ballast to a certain degree. I didn't like the overall quality. I ordered mine from inductionlamps.com they no longer offer that fixture to my knowledge.

Indution florescent lighting is what these are, no electrodes to burn out but, alas no good proven grows with them and they are su much cheaper from china for the exact same light :-)

So now it looks like my theory of green light added for quantum growth is starting to be proved here as the spectra have a lot of white in the unit(so more green spectrum than the blackstar) and the penetrator has dedicated green bulbs also. Haha love it when a theory is being proven. :-) . My next grow has just gone into my flower room today so I'm gonna buy a couple of green cfl's to supplement my two 500watt blackstars and see what happens.
