When it comes to appearance, LED tubes look exactly like fluorescents. However, they are very different. First, LED is a mercury-free lighting solution. There are no costly recycling fees associated with LED li
Compact fluorescent lamps, or CFLs for short, contain argon and mercury vapor housed within a spiral-shaped tube. They also have an integrated ballast, which produces an electric current to pass through the vaporous mixture, exciting the gas molecules. In older CFLs, it took several seconds for...

The eyes of the general public, as a new type of lighting technology, LED basic and energy has been equated with the equal sign.
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...
How Are Compact Fluorescent Lights Energy Efficient? How do CFL materials work together to create an energy-saving light source? The ballast helps regulate theflow of electricity to the bulb. At the same time, the mercury gas creates an ultraviolet light when it’s excited by the electrical cu...
However, it is one of the best returns on your investment when you convert over to energy efficient lighting, like LED. Payback can be under 1 year given the proper operating parameters. And we all heard the easy marketing catch phrases, “Low Hanging Fruit” and “No Brainer”. But it ...
High end LED fixtures use complex circuitry to precisely spread electoral voltage over drivers, which control each emitter. LED lights properly driven will give precise energy quality and not lose or shift energy (spectrum) unlike ALL fluorescent lights. ...
They have come down in size a lot then :) In the mid-70s I recall the unpolarized ballast capacitors in fluorescent tube fittings were also the size of a cola can and were only about 8 uF (they were spec'd for 250 V AC continuous). Title: Re: How to connect the output of...
