Comparing LEDs to traditional light sources actually can be done relatively easily. Below is a general rule that can be followed when comparing traditional light sources to LED.
If you have questions about equivalent light sources we are here to help you via email or phone on the contact us page.
A Shape Incandescent Lamps--Approximately 7-9 times less wattage is required for LED. For example a 10W A Shape LED is equivalent to a 60W A Shape Incandescent. The same will hold true for all incandescent lamps including R & Par shape floods, Decorative Lamps and others.
T8 Fluorescents--Approximately 1/2 wattage is required for LED. For example a 34W fluorescent tube can be replaced by a 18W LED Tube.
Metal Halide--Approximately 1/3 wattage is required for LED. For example a 120W LED fixture can replace a 360W Metal Halide.
HPS--Approximately 1/3 wattage is required for LED. For example a 50W LED can replace a 150W HPS. In addition the LED light source will provide a substantially higher CRI resulting in noticeably greater light quality.
