LED "Bulb" Fits Fluorescent Tube Fixture

At Last, an LED “Bulb” fits effortlessly into existing traditional fluorescent fixture. Retrofitting from fluorescent to even more efficient LED lighting in the ubiquitous ceiling fixture has to date meant buying a new fixture not just replacing the bulb.

The Aleddra EasiRetrofit Double-End power tube solves the problem. No need to change, the original double-ended wiring fixture. Just insert the LED tube.



“Only Aleddra offers a safe alternative that is also energy efficient: a UL-certified double-end power LED tube.  Aleddra's EasiRetrofit tube utilizes a safety switch on each of the two end-caps on the tube.  This patented design eliminates the risk of electric shock to the installer, and keeps maintenance employees safe in the event that they mistakenly insert a fluorescent tube into the converted fixture," says Aleddra Sales and Market Manager Matthew Maa.

EasiRetrofit G3 tube also has what the company refers to as a “field-replaceable driver.” It enables the user to replace the driver when it dies, thus effectively doubling the tube lifetime to 10 years at an incremental cost.

The lighting tube is available in standard 2-foot and 4-ft lengths. Color temperatures include 3000K, 4100K, 5000K, and 6000K.

For those who want to know more here is Maa’s technical explanation:

Many lighting professionals and facility managers have long been puzzled on the question: What would happen if a maintenance crew re-inserts a fluorescent tube into a fixture converted to be used with an LED tube only. The answer is "it depends how the fixture is wired," according to , who performed a live safety demonstration at LightFair 2014 on this issue. Maa explains, "if the user retrofitted the fixture for single-ended LED tube and therefore converted the fixture to single-ended wiring, then inserting a fluorescent T8 into such fixture will immediately short the bi-pins of the fluorescent tube and thus damage the lamp. At 277V, this instantaneous electrical short may cause the fluorescent tube to explode.  We have seen these events occur.  In many cases, maintenance crews do not realize that the fixtures had been converted to single-ended wiring LED tubes.  The use of single-end power LED tubes for retrofit is a serious safety hazard, and a liability to employers."
