Bill, they both beamworks, first one has 3 rows of light, 1700 lum, second has 5 rows and 2800 lum.

so which one? Second one is brighter, and both same brand. So if you could clarify for specially challenged people that would be great im going to order as soon as im back.

and... I AM going to pick up my tank now! Oh yeahhhhhhhh!!!!!!!!!!!! Timing couldnt be more prefect, as of 3 hours ago im on holidays! And what can be more perfect way to spend holiday them doing a tank!
