Guide To Selecting a Screw-In Light Type
Step 1: Look at the picture below to figure out what type of light it is: metal halide, halogen, incandescent, etc.
Step 2: Find the light watts or bulb size by looking on the bulb or the box: 320W, Par38, etc. Tip – the easiest way is to find the box of replacement bulbs in the maintenance closet.
Examples of Common Lights
Incandescent Light
Incandescents are cheap to buy but waste lots of money. Your electricity bill are 3X more than if you used CFLs. On top of that, incandescent bulbs burn out in a few months where CFLs can last all year. That means incandescents are also costing you extra in replacement bulbs and in hours of maintenance time.
Incandescent - 60W
Incandescent - 90W
HID Lights - High Bay Lights
HID means High Intensity Discharge light. When used indoors, HID lights are primarily installed as high bay lighting. High Bay lights means they are mounted on high ceilings. High Bay HID lighting is typically found in warehouses, storerooms, and factory floors.

LED Lights - Halogen Light - Track Lighting
Halogen lights are often used in track lighting or as accent lights. LED lights are best as alternatives for halogen lights because LED lights are great at lighting a focused area like track lights.
