As a previous manufacturing engineer, I would bet that in mars r+d department there are lights and diodes from all or at least most other competitors, they know where they stand !they know they are overpriced and subpar quality. They don’t care about our opinions they just want their name mentioned Not sure why we all continue to help with the negative publicity? It still gets people saying mars ! More times we say it and more times we write it the overpriced stuff they sell!
I’m tired of all the untruth they put out we are not ignorant, I guess they support the farm, so I will be respectful, by trying not to comment on their products or ethos again hope I can do it!
Yup. And as far as advertising cost it is quite minimal on social media compared to any other method.
And their labor and materials also very low.
Smart but I wish it was transparent to more people.
I am hoping that running them at about 80% power, and only 12/12 , that they don't begin to dim anytime soon.. I love the expensive Electric Skys, but at the progression rate of LED's can't see spending the big $$ on them.
Wow..Sounding like a reformed smoker telling it like it is!I'm running my panels at about 75% at 36" above canopy. Drivers are mounted up high near exhaust. Oscillating fans blowing over the heat sinks.
I would be running HPS at 100% at 18" from canopy with much, much heat.
And replace bulbs every year.
Lol. Mine are at about 90%. I cranked them up full then backed them off about 1/8 a turn. I still need to work at mounting my drivers outside the tent, but that'll wait till after my current crop is done. Even 1/8 dimmed, I cant really notice the difference visually. Though there is a difference, says the lux meter, and a bit less heat too
I was thinking of trying water cooling the fixture, like I do with my PC's. But figured that's too much.
Water cooled leds have been around for a bit. I remember looking at some last year?
I'm sure they are, most things that can be cooled have been cooled by water at some point....
Personally I feel like if they need to be cooled then your losing efficiency through heat. More diodes, closer and at less draw would be better than increased wattage to fixed number of diodes....
I think that that might be a good question to ask your Insurance company..not mentioning growlights, but the just ratings and liability aspect.Not a Kingbrite question, but since you guys seem to be the most knowledgeable on the subject thought I would post this here. Looking at the HLG550 ECO as possible purchase. My question is how big a factor or safety concern is the ETL rating? I would assume all the parts are UL rated, just wondering if the ETL rating is really that important, like burn my house down important?
I was talking about cooling beyond factory specs. To increase the lifespan of the LEDs. Not sure what you're talking about.
It was a thought experiment only..

For sure. Just saying they are doing this already. But I believe it
Would be more efficient to use more diodes at less power negating the need to cool and allowing for maximum lifespan
It's so weird to me that growers buy leds instead of building them.
If a led burns out I just replace it with my soldering iron.
I guess we never were building HID lighting for the most part either. I don't know why I thought LED meant people would be custom making all their lights, but that's not how it worked out.
