Try and find out how much power it uses so you know what you have. A 3x3 is a great choice even if it doesn't cover the whole tent, you don't have to fill it wall to wall. Its always nice to have extra space
hey
the guy is 100% right but he forgot some ?s that would change that answer
1 what is the light shape .......rectangle or a long thin bar or a square
2 LED as in diodes or as in cob(one chip with a lot of little diodes)
3 what is the lens angle for yours.........120 90 60 or mix
u can always post the name of the model u are using letting ppl look it up .......but those 3 questions will effect the right answer
if u are a square/rectangle light with led diodes on a 90 degree lens the guy is spot on
