I have a feeling the se250 would rock the shit out of my tent, but now im not so sure i seen the 900 which is huge does a 5x5, so i would imagine half the watts of 900=450 would cover 2.5x2.5 thats just My train of thought, not sure if it's right but sounds logical too my stoner brain lol.. would i need almost 450W to cover a 2x2? How could a 250 cover 2x2 when a 900 only covers 5x5? I just wanna buy a God dam light some one help me. Lmao
