great deal, really is only bout 20-30 bucks more. includes bulbs--->

10,000 lumens roughly double the output of T12 and t8 2 bulb fixtures plus t5s are the most efficient flouro light available.

cheaper per bulb than the 4 foot 4 bulb they have. id just get one of these and get more of em when/if needed in future.

at least now you educated OP, now the choice is all yours
