ONE DIRECTION IS MORE EFFICIENT- If your fixture only projects light in one direction, why waste energy sending light where you don t use it? You can often use 20-30% less watts with a 180 degree bulb compared to a 360 bulb. The 115 watt is a great upgrade to a 400 watt Metal Halide or HPS bulb. Rotatable base allows you to aim the light where you need it.
