**ULTIMATE LED TEST** *GLH Spectra 290* VS *Blackstar 500* VS *Hydro Grow LED 336X*

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

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....

but i fixed my pannel and sold it i had it open they look nothing like a cree light. it was a bad solder point. and piss poor drivers as well
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.
www.ledgrow.eu
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?
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.
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 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"
