Well I decided on a perfect sun dwarf star ..it will cover a 3.5x3 footprint.
I have a PerfectSun GOLIATH, and am totally happy with it. Built extremely well and have had mine for over a year zero issues.
Check out Videos on Youtube with people's results using the PerfectSun Dwarf Star. The results speaks for themselves. Granted you need to know what your doing...but that holds true for any LED.
Also, it's important when shopping for anything to look at the warranty. Does the company stand behind their product. Many of the other LED companies only offered 1 or 2 year warranty. PerfectSun has 3 year warranty - covers parts and labour.
How many other companies are out there with YouTube videos of what their product can do? And providing PAR readings.
Lastly, Neil of PerfectSun LED has done alot for the growing community (420 Magazine), and shared alot of knowledge from what he's learned about growing, and he doesn't keep it a big secret. He has quite a few videos of different strains, and what he's been able to accomplish, and how he's done it. He's pulled some insane yields..check out his videos on Youtube...he knows what he's doing.
Again, I don't work for the guy or have any affiliation with him, other than I bought one of the lights and would do so again if and when I need another one.
Congrats and enjoy your PefectSun.
