The lumens are important in knowing how much light you need for your space.

try to keep it above 5000 lumens per sq foot

Watts just let you know how much your grow is going to cost in power.

If you are going to have a largish grow 400+watts. try to go for MH and HPS they will be cheaper in power in the long run.

ALso, Disregard the "equivalent" wattage.

So your bulbs are 15W equivalent to 60W.
Forget the 60W, itâ??s just a marketing tool so that you know which bulbs to buy to replace what in your house. When telling people what your using, use the Actual power consumption

Here is a Thread I made regarding power consumption and the cops.
