Watts Only Tell You How Much Electricity Your Grow Lamp Uses

Watts tell you how much energy your lamp is using and how expensive it may be for you to run the lamp. You can use watts to estimate the size or quantity of lights you may need. While a lamp can seem very powerful because it uses many watts, if it is not efficient, it may convert too much of that electricity into unwanted heat instead of light.

If you base your lighting choices purely on wattage, you may end up with an unnecessarily large electricity bill and a lot of wasted energy in the form of unwanted heat.
