Nice job…Czech growrs
im building a 690 watt led panel that costs me about 800 canadian itll be cheaper in the states since i got most of my stuff from there and had to pay retarted shipping plus a customs fee
Yeah, that durability and lifespan are still a questions. maybe its luminosity will decrease also over time. it would be fine to measure it regularly with lux meter to see how long it will last.
Good job!
Its already dry, and its 348g of tasty citron diesel smoke. 
Thnx for watching

Wonderful… thats is easily comparable to HPS! Really good for 300w! Btw do you have chance to measure watt power consumption? I wonder if it is exactly 300w or how much is “energy overhead”…
Great test ! Thanks for sharing!

Power consuption in full load is 341w. Hps has about 420-430 if im correct.

if the panel is made with cree cobs and meanwell drivers the light will last you a long time unless you short circuit something. no need to regulrly check the light output
Yes, meanwell drivers are installed. So good thnx for information.
