mohawk is right cree is not used in black star two of my 3 black star pannels died well half the lights anyhow. they are poorly made thats why there cheaper. they work good due to proper angles and spectrum but the lights arwe cheap and there warranty sucks. if you have or use a blackstar always have a back up light you never know when its going to quit

uh oh, be prepared to be attacked by the blackstar defenders for not posting positively about those lights.

I've been following that on and off since the beginning not a big fan of his spectrum look at his plants scraggly stretchy growth and to my knowledge and I admit to not reading every page there I have not seen any decent results from his panel at all.

As for the other panel At 700 pounds for a 280watt draw light that's fuckin out of control expensive 1100 dollars for 300ish watts of draw that's approaching penetrator territory no thanks I'd rather build my own using Crees and Luxeon and SETI LEDs which the latter being ass expensive for UVB on the panel if I was going to pay that much and have a more full spectrum than that panel

That being Said I'm sure that panel would perform excellently

Yo kaptain kron this guy from www.ledgrow.eu is improving day by day you should look at his results also these other sites like

http://www.prakasa.co.uk/index.php

http://www.growstealthled.com/Gs600-Quantum-P43C8.aspx

http://www.ledfusion.co.uk/

http://www.plantphotonics.com/ (is very pricey but i think the prices need to come down for people to try them out)

thanks thought it was so how is it like in veg? any good as it is confusing having to use the veg light for vegging and flowering light for flower production. i'd prefer a light that is good for veg and flower.

Sorry to hear u have had problems man I've had nothin but good luck with my panel but just cause IRS died is no reason to say they aren't using crees there's many reason they coulda died most likely a bad solder joint. Don't blame the led blame quality control in china on their workers. I know lots of people wih these lights and not one complaint ive only seen three people on this forum even say they died. I've had mine since my join date basically and not a single issue

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....

I am using a 900w flower Blackstar in my mother tent, which is the same hue as the 500w flower, just more lights. It's doing good in veg so far. I haven't used the 500w in veg, only 240w High Outputs (veg model) and the 900.

so you have a 900watt flower model in your mother tent and a 240watt veg model? as i did read you had 2 led panels in the tent so 1 900 watter and a 240 watter is that right Wejuana!

No currently just the 900w in the mother tent. I am currently using a 240w Blackstar over the EZ Clone 30 machine, and 1 Blackstar 240w and 2 Spectra 150w to veg the 2nd round of LA Con clones.

no one checking these sites for these led panels? meant to be good for price and results one of the sites are comparing the spectra 290 with another 300 watt model from growstealthled.
Have people on this forum used the prakasa led panels?

I have heard of Prakasa, very good things actually, but I haven't personally seen them or had any experience.

Ok, so ebay says one thing, and gotham's site and lighthouse hydro's site both don't mention CREE LED's.... seems at least worth investigating...

plantphotonics leds are cree but i hope to see a grow with these bad boys. Sold on ebay £200 for 70 watts.

and check out www.ledgrow.eu this guy has independent tests showing him grow his herb with the lights he is making and testing.

Plantphotonics uses this:
red 630nm is cree xp-e
red 660nm is Ledengin 5w driven at 3w
the mix of the two blue is bridgelux
the white is cree as well

THE GUY IS OFFERING REALLY GOOD PANELS
IT'S WAY BETTER THAN ALL COMMERCIAL LED PANELS, HONESTLY!

yes I know, they are some pricey. I AM TELLING YOU:
with good diodes, you need less watts for good results.
check this thread out, "stealth cabinets". It's here on rollitup, a guy is using the 280w panel

Also, the theory of narrowed degree angles goes to hell here;
with cheap diodes, it is a valid one.
But with good diodes (CREE XP-E is 130 degree angle, osram golden dragon is 170 degree angle) PENETRATION AND GROWING IS ALL GOOD!

There is an other amazing thread you can learn a lot from, there is this guy using a diy osram golden dragon panel
"DIY LED osram 175 watt soil"
