Second hand lighting and an odd sized tank.

[Saltybubbles288]

I have a 30 inch cube tank with two second hand leds the are blue/white and are rated for 255w on 100% they are sitting about 6 inches from the water at the momment centered over the rock formation, what im trying to figure out is how well lit I could consider this set up, and if it's poor if some type of reflectors built into the hood would help? Or angling the lights towards the rock? The lights don't have any manufacturer info on it other than wattage and LCD info. I'm pretty new to the actual process of setting up a reef system and would appreciate any help.

My advice is to get a PAR meter and test it out, better safe than sorry.
