Best 600watt flower bulb

[Reefer126]

Hey peeps Im wondering what is the best 600 watt flower bulb? Is there really much difference between all the brands or is it mostly marketing hype?

If you want the "best" possible bulb, regardless of cost, I would google some studies that are conducted (mostly by bulb manufacturers). These studies, and I have read a few, all seem to consider the light spectrum available in the bulb, and compare that to the light needs of the plant, and they come up with a winner (usually their own bulb).
There are a lot of good bulbs and if there was one that produced more product that all the others, there would be only one bulb out there. My 2c

I use two 300 W Sygavled with my first hydro grow and its going well. Lights run pretty cool, very compact, just plug in and hang (comes with cables).
A little over $60 USD each.
Keep 18-22 inches away, farther for starting clones.

Thanks for the info, I currently use an ipower 600 watt and it does well.

I just saw a 300W, LED, 5000 Kelvin in a local Ace Hardware for $39. Screw in with 6-8 bulbs. Would have bought it, if I needed another 300 W.

I have a 600w HPS that does well but i have been eyeing the 315 or 630 LEC setup. I have a 4X4 so it's just a matter of the light spectrum i want for the space.
