I am Area 51, though I am not here to sell anything to anyone, or convince anyone which light is better or worse.
You are correct, panel size has a lot to do with footprint of the LED lamp, actually as much as the power coming off of the lamp. You need a good balance between panel size, LED power, and proper beam angles to get the best out of the panel. The SGS is pretty large for only drawing 155w. They are close to the same size as the 900w Blackstar.
Fero Canada and Area 51 were associated during 2012, but have parted ways. Fero Canada and Fero Europe has parted ways as well. Fero Europe has become a distributor for the SGS lamp, but otherwise are not partners.
Faux means fake. Cidly uses Epileds and Optotech, just like 90% of Chinese sellers. They are okay LEDs, they do grow plants. But there are better out there. I know they're fake because about half the colors Cidly offers aren't even made by Epistar or Bridgelux.
Most Chinese LED grow/aquarium light factories encapsulates their own LED diodes right on site.
As for using white + red only, we've been doing that for a while now, almost a year. We dropped the deep reds a few months ago because Cree NW/OW white has plenty of deep red, and not all plants respond to
a lot of deep red that well, but all plants respond to regular red quite well.
Yeah, my bad about the area 51 part. I know all lamps get reduced micro moles as you move away from the center, my point was that due to the small footprint of leds, that fact becomes particularly relevant in the led case (6 inches away from the center in an led has a larger drop in par than 6 inches away from the center of an hid lamp.) I know fero and area 51 are associated, fero is now selling the new area 51 all cree led. I remember reading on their site that helioto was the bomb and epistar and bridgelux was crap, and now their selling apollos with bridgelux and epistar; I dont get it. What is faux bridgelux? Do you have inside information on area 51? (that sounds funny.) Do you now what made them switch their spectrum to only white and 630nm red?
Besides Cidly spamming the crap out of my email, my problem with the Apollo's and any Cidly LED, is their use of 700mA. The LEDs they use max out at 700mA, and when driven at the max, they have a much shorter life, and will not run at their best capable efficiency.
I think the Magnum plus2 is the same as the Bysen, mainly because Bysen had theirs first, then Magnum came along with a similar model (same LED modules with 8x 1w Cree's in the center of 12x Epileds, same dimensions, Magnum's case design) I'd buy the Bysen over the Magnum or the Cidly. Vanqled seems to have some happy customers too.
My buddy is probably harvesting within a week and Ill post the results here of two helios 6 modules each 350 total watts of led with a couple of cfls to throw in some white. Its basically the same magnum plus2 but split in half although I dont now what frequencies magnum is using. He is planning on next run doing these helios with two apollo 8 (500 total watts more). So, eraserhead, if you have any info or reason why he should reconsider buying from cidly please let me know since they have not been purchased yet. Oh almost forgot, there is no way I could convince my pal to supply me with pics. He is a ninja when it comes to security.
