Graphene coated LED and OLED - the future?

I just dissected a Philips 7W filament LED bulb that produces 800 lumens with the frosted glass bulb on. About 114lm/W for a cheap, off the shelf bulb that is 4000k or 5000k color. From what I read, graphene coated LED filaments are a thing and they are efficient. Not sure if this one is, but the value to efficiency was worth noting. Probably better now that it runs with no glass bulb.

Does anyone know of any OLED components or OLED lights and their efficiencies? I'm reading that it's all the rage for TVs and phones, but not yet for horticulture and they keep stating the improved efficiency but I can't find any lumens per watt numbers on a white full spectrum light.

F strips and Quantum Boards bro :lol:

But seriously, you may be on to something looking at other forms of led. What does the spectrum look like on those types of products?
 
People here raged hard on me for trying to bring 140lm/watt bulbs to their attention. Nearly A YEAR AGO. That's 140 with the bulb on. They do pretty good for veg, nearly a 4x4 with I think it was 72 watts.

Oh and these are 2700k.
 
Nice. Well here in CanadEH our leds are expensive. I got an led garage light that is 110 lm/W for 1$/w after tax and felt lucky.

Those philips bulbs were 6$, my 27w garage light was 28$ after tax and does a nice 5k

Damn. The ones I got were 20$ for 4x 11 watt bulbs I wanna say. Maybe 24$ tops.

I didn't cut the diffusers off as they work great with them on and figure it would make good diffuse light without hotspots
 
With lights with unknown spectrums lm/w doesn’t mean much. If you were to compare same spectrum lights then ok. Having said that cree cobs works well for me. Philips 14w leds was good for the bonsai mothers and vegging plants too. I’m not completely sure about how oled works but they cost shit ton of money to manufacture so it would be pointless to use it in an horticultural application at this point.
