CAMBIO LEC POR LED

try to use an evaporative cooler, much cheaper than LEDs, it will control the humidity and temperature

Also I like GB shop. Green Brand or Growbarato. Good options and some nice discounts on the cob leds and quantum board with their own brand. I've a friend with 300w from Mars Hydro but I wouldn't trade my lec for that. It's good but the lec keeps me warm in winter and doesn't burn in summer as long as I keep good ventilation in the tent and outside.

Have you tried using a cooltube and ventilation on it sending the lamp air outside tent? It could really improve temperature inside the tent and be cheaper than a led. To buy a led that gets you the same result as that 315w lec will cost you a bit more. I've checked out cre.science website. They let you build your own (custom) and send you the parts to assemble. Trust worthy high quality. I found that in aliexpress there's some trust worthy suppliers with good prices but I wouldn't think of spending less than 300€ to replace that lec with a led.
