Our premier product, the XR-10 is the world

The CL-5 Bulb like all EarthLEDs is amazingly efficient. It only draws 5 watts of electricity, while at the same time operating below 125 degrees Fahrenheit. The end result is reduced cooling costs and operational safety above and beyond that of traditional incandescent bulbs.The revolutionary CL-5 is a great choice for anyone looking to replace an incandescent bulb housed in a lamp. Direct dispersion bulb technology provides a truly natural light pattern. With a high output 5 watt light engine, the CL-5 will provide light equivalent to a 60-65 Watt incandescent light bulb in the Cool White Version and 45-50 Watts in the Warm White Version.
