The T in fluorescent lighting stands for "tubular." The number that follows references the diameter of the fluorescent tube in eights of an inch. Therefore, if you have a T12, it is larger by a half inch to the newerT8 tubes.However, the diameter is not as important as the bi-pin b...
So, if you are still using fluorescent lights in a commercial or industrial facility, a lighting upgrade to LED lights can cut your energy costs by half. A very common upgrade we help with all the time is converting fluorescent T5 high-output high bays over tolinear panel high bays. At t...
Date Feb. 1, 1996The method operates at least one fluorescent lamp (FL) using an electronic ballast. The ballast has a rectifier bridge (GL) which has AC mains voltage (L, N) across it, a connected step-up converter (L1, D1, V1), a half-bridge circuit (V2, V3) as well as a...

The sockets that hold the tubes in the fixture, like any other part, can fail. This is seldom the cause of fluorescent fixture problems, but it does happen, and new sockets are easily found. As always, remove the old sockets (see How to Replace a Ballast, above) and bring one to the...
One of the easiest methods of designing better lighting, is to simply change your light bulb. But not all studio lamps are created equal. From a £5 hardware store fluorescent tube to a £1,500 bespoke solution, the choices you make affect your ability to match colours accurately, judge...
This is not only due to the photon energy (light) output, but also due to the amount (quantity output) of specific energy frequency of light (photons) LEDs are able to provide for input energy used without the light energy restrike ALL fluorescent lights have to deal with. ...
