Amare Bar-8 or Bar-6 upcoming Gen-2 is at the top of my list. They'll have more efficient diodes then 301h and the most complete, comprehensive led growlight (not human light) spectrum to date. Its the highest build quality available that i am aware of as well as the most versatile fully detachable fixture available. Now with x6 remote drivers instead of x4 & more tricks then the first gen. Farthest diode spacing i know of in the industry on a bar light as well as thickest thermal mngmt. & has gasgeted glass covering for an IP-67 Rating. They Have provided an enhanced Sunlike as possible spectrum for 8 yrs called the "Equatorial Spec" and it has only gotten better with technology. The spectrum is fully included into each 120w bar. No supplemental needed. These are custom made not rebranded. Veg & bloom modes, sliding, swiveling, detachable bars allow for a 6.5'x5' coverage, stand alone. 7x6 with crosslighting. Uva on a seperate, dimmable channel including ac outlet for a timer. Upcoming models have my touch to the spectrum. One they wanted to do since day one but technology & cost did not permit it. Cost is still very high to make this new spectrum alone but he made one for me custom as well as the whole next lot of Gen2. Bar-8's. Usually $1.64 or less a watt when buying direct.
There are more poular lights out there that have not been around as long. With website under construction & no social media going not many know. Most companies are relying on customer feedback to upgrade each yr. instead of knowing & doing to begin with. Owner is a grower & tested this stuff himself many moons ago.
Sales does not represent quality imo. That would be like choosing Amazon's top-10 of the yr.
Good luck!. I have info not available yet from the company if you're interested. Lost all my flower pics. Were documented here on a thread thats MIA.
