I do not have a "Pro" light meter so am using an app on my samsung note 5 called "Light-o-Meter" while I know this is not a precise way to measure it does give side by side comparison of the lights. At 24 inches away, the first light measures in the 10,500 lux range the second light at 24 inches measures around 12,000 lux. thats is around a 15% difference in two same lights or 15% dimming in two weeks.
In the photos, the one on the right is the first in use, the left is second in use
MAX at customer service saw my review and contacted me through Amazon. Max was concerned that I was not completely satisfied with my purchase and wanted to make it right. After a few emails between us Max diagnosed the issue and sent the parts I needed to replace and bring the light back to 100% plus spare parts in case there were future issues.
Thank You Max, You have been very helpful
I will openly recommend this light to anyone who needs a Full Spectrum LED indoor Light source.
A Company that reaches out to a customer to fix an issue is not what I am used to. From now on, I am thinking I will only deal with this company for any future LED lighting needs
Update 5(10/23/2017): Just got the new LED chips, which work, however because the fans died as well it's still no good for me.
The power draw might be a little under what is listed but give it a week or so of usage before testing again to see how it works. It should get better in that time.
Update(Oct/9/2017): More than half of the LEDs have failed after less than a year. See how in the images one side is almost completely non-working, and the other has at least one line of failed LEDs?
Update 2(Oct/11/2017): Contacted Seller, they're going to send me replacement LED chips. Still disappointed that they burned out in under a year, but the service is very nice. Will go up to 4 star when they arrive.
Update 3(Oct/12/2017): Less than a day after contacting the manufacturer the entire grow light has become completely non-responsive so the point that replacing the lights clearly wouldn't be enough to fix it. Back down to 1-star for now.
Update 4(10/17/2017): GalaxyHydro, which is apparently also Roleadro, offered me a discount on another product. My issue is still unsolved. At this point, I firmly suggest avoiding this product and company.
And for the price it's a super deal. If I ever have to replace any lights, it'll be with these.
