I came across these LED's and I just want any ones opinion on these or LED's in general.
As I have tested, LEDs in general are a very good and efficient way of plant lighting.
Unfortunately, all of the ready-to-use LED "grow panels" are heavily overpriced. And overrated in many cases. And pure China crap in many cases.
The main problem of ready-to-use grow panels ist, that those are built from the cheapest LEDs on the market, not from the best. So many customers are not satisfied with such lights when used for plants with high demands of light.
I can only recommend to solder do-it-yourself LED lights, using the best and most efficient LEDs on the market.
My growing experience with LEDs is about two years now. But as high efficient LEDs are not cheap, I only use them in very small setups (5 watt) or even just for "one plant in one glass" (1 LED = 1 Watt = 1 plant). The LEDs I use are CREE XR-E "cool-white", and depending on the temperature you can keep (at least) Cephalotus, Dionaea, different Drosera, Utricularia and Nepenthes under such lights.
But compared with fluorescent lamps you cannot save as much light as it is often claimed by the sellers of LED grow panels.
My estimate is, that it depends mostly on the type and quality of the reflectors used with fluorescent lamps, how much electricity you can save using LEDs instead:
Using no reflectors with your fluorescents at all: LEDs can provide same light with 50% less electrical energy
Using bad or blind reflectors with your fluorescents: LEDs can provide same light with 25% less electrical energy
Using brand-new and best optimized reflectors with your fluorescents: LEDs can provide same light with same electrical energy
At the moment, I see advantages for LED lighting only for very small setups, as the lights take very little headroom: A CREE XR-E on a hex shaped mounting plate is about 6 mm thick, and if you glue that onto a 3 mm cooling plate the total hight of the light is about 10 mm (less than half of an inch).
BTW: The panel you are interested in has "3 Built-In Cooling Fans", do you like lights that constantly make noise when in use? I prefer noiseless passive cooling with big metal cooling elements and no fans.
