Theres maybe 3 companies out there providing third party testing. Give or take 2 by another doing it for them.
When you make a spectrum specifically designed for efficiency over results then you can bet sure as hell they are gonna get it 3rd party or whatever it takes to brag about the "electrical efficiency ". Which is only half the battle man..
Results & quality big guy. All that matters to me with a good warrenty from a solid company with no complaints, only happy folk. Go on insta or FB. Other forums.
Mktg is shy. Oh well.
3 companies? Heliospectra, fluence, gavita, nextlight, hlg, chilled, highlight, bcblonde, plc, timber, lumigro,valoya, osram America's...3rd party tested, off my head, others I probably forgot.
What's the problem, "Victor" can't scrape a couple hundred together to verify forum claims? Tell him not to worry, China factory sphere will be close, lol
IDK where you've been the last couple of years? Output is still king , de hps says hi, most electrical efficient hid. Same with other techs, generally speaking.
