LED wattage, energy consumption, and electricity cost guides.

LED lights use 2 to 20 watts depending on type. A 60W-equivalent LED bulb uses only 8-10 watts. See the full wattage chart for bulbs, strips, and fixtures.

LED bulbs cost $2-$8 each. LED strips run $10-$40 per 16ft roll. Total ownership cost is 70-80% less than incandescent over 10 years.

LED lights waste 15-20% of electricity as heat and convert about 40-50% into visible light. Incandescent bulbs waste around 90% as heat.

A 15A circuit can power up to 180 LED lights at 10W using the 80% rule (1,440W usable). Most homes can run all LED lighting on a single 15-amp circuit.

LED bulbs run 100-150°F, warm but safe; incandescent bulbs exceed 400°F. LED strips stay 90-120°F. See full temperature guide by type.
