A CFL (compact fluorescent light) bulb of almost the same lumen capacity (125 lm) requires only 3 watts of energy, producing 42 lm/W. A metal halide light bulb is even more energy efficient, with some halide bulbs generating as much as 115 lm/W. Light bulb energy usage is imperative when considering how much illuminance is required for a room versus how many lighting fixtures are possible. Furthermore, as wattage is increased, so is electrical resistance, as illustrated by the Ohm's Law derivation R= P/I2 (where R= resistance (Ohms), P= power (Watts), and I= current (amperes)). When calculating the amount of lighting required for very large rooms, therefore, or rooms with high ceilings, these basic physical laws must be accounted for.

You don't have to go too far with it, but wipe down everything in the room, including the projector so your lamp won't get taken over by dust and have a blow out.

I was happy with my purchase, as I had found a way to provide two plant lamps for my little seedlings for less than $50. They weren't commercial grade, but they should work.
