LumenMax3--switch from 250w to 150w?

[kalosbios]

Hello all,

Need some lighting expertise here. . . .

I have a LumenMax3 DE pendant I would like to use for a mixed reef over a 20H.

Though I could use it as is, I just think it's a little overkill for that size tank; I don't want to have to suspend it so high, for that tank, that the light spills out excessively into the room.

It is a 250w model--can it be changed to a 150w pendant just by switching out the bracket inside? Could someone explain if so?

Thanks for the advice,

Gordon
