The circuit is based on IC1, which is a 555 timer IC in astable mode. It will power a 6 inch 4 Watt fluorescent tube off a 12 volt supply, consuming 300 mA. It may also be powered by a suitably rated universal AC/DC adapter. Advantages of the design are:.... -
This is a low-cost project for 20 or 40 watt fluorescent tubes. However the most efficient is to use a 40 watt tube (or two 20 watt tubes in series). It's a circuit you can put together from junk box components or build from a kit. It's very simple to build.... -
Here is the schematic diagram for a 20 Watt driver. I developed this circuit in 1985, and used it to build a lamp that found much use both as camping light and as emergency light during the then-frequent power outages. The two transistors work as a.... -
This inverter is very easy to construct, reliable, and even powerful enough to light up a 15W florescent tube (if you cool your transistor well). The only hard-to-find piece of this baby is the so-called yellow inverter transformer. It's a miniature high.... -
The lamps are usually used as ballast or electronic ballast inverter. Here it is used to reduce voltage capacitor reactance. Interesting is also the method of ignition of the auxiliary electrodes involved over 150 Ohm resistors. To start simply involve only.... -
This is a Circuits of fluorescent lamp with a power of 40 Watt - The ambit works abundant like the aboriginal Strobos. except that a beaming tube is used. Thus, the beaming tube zG ndbereit charcoal constant, the two electrodes of the tube are continuously.... -
In this article I will offer driver circuit for 12 V/5Watt fluorescent lamp, this circuit used a normal 220 to 10V stepdown transformer in reverse to step 12V... -
The circuit was designed to experiment with using small fluorescent lamps as a broad pattern source of modulated light. The circuit hits the small lamp with narrow 1us pulses at a rate of 10KHz. Each pulse launches about 10 watts of visible light. The lamp.... -
This is a audio-controlled lamp circuit. This circuit requires low voltage input such as pre-amplifiers, tone control, or general audio line level output. It`s... -

This circuit is basically a 8W inverter circuit. The circuit continues to be intended to drive an 8W fluorescent lamp from a 12V power supply, utilizing an cheap inverter primarily based on a ZTX652 transistor. The inverter will operate from supplies in the.... -
While they have been with us for many years, fluorescent lamps remain somewhat mysterious to most people. This isn`t really surprising, since their operation isn`t simple. The tube itself contains a mixture of gases, but the active ingredient is mercury..... -

This project was deliberately aimed at developing a very low cost cosmic ray detector using common Fluorescent Tubes. It was based on variation of an experiment performed in 2000 by the CERN (European Organization for Nuclear Research) laboratories by Dr..... -
Compact Fluorescent Lamps [CFL] are low in price, plentiful and easy to find. Unfortunately, the current crop of these lamps seldom lasts as long as their warranty. Usually only the electronics fail and the lamp part of the bulb assembly are still very.... -

A fluorescent lamp has quite a few unique requirements to get it to start up and stay illuminated. How does this flyback converter manage to do these things I had first looked around to see if I could find a schematic for this fluorescent lamp assembly, but.... -
Typical F71T12 100 W bi-pin lamp used in tanning beds. Note the (Hg) symbol indicating it contains mercury. In the US this symbol is now required on all fluorescent lamps that contain mercury. [1] Inside the lamp end of a preheat bi-pin lamp. In this lamp.... -
Whenever there is a need for battery-powered lighting, like for camping, solar powered cottages, cars, boats, planes, or emergency purposes, fluorescent lamps have a great appeal. Firstly, they are very much more efficient than glow lamps, so they produce.... -
A number of people have been unable to find the transformer needed for the Black Light project, so I looked around to see if I could find a fluorescent lamp driver that does not require any special components. I finally found one in Electronics Now. Here it....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -

This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
