Always replace a defective electronic ballast with EXACTLY THE SAME as the one you are removing. This will ensure a quick changeover with no extra work needed. An alternative could be a different size and may not fit into the space left by the original. If it does fit, it probably means re-drilling the light fitting to make new fixings to secure it. Also, an alternative may not have the same amount of connections on both the ends. This could mean extending or making adjustments to the wiring in the light fitting to compensate for the differences. If the ballast is used in conjunction with other control gear there could be other considerations to be made. You should not attempt to do this type of work unless you are a qualified electrician.

The manufacturers of the electronic control gear (ECG) that we stock will be recognisable to everyone in the electrical industry. They have many years of experience and are well known for their basic and advanced high quality products. From the standard Osram and Tridonic control gear that is used with the T8 fluorescent tubes. To the Osram dimmable gear for T5 and T8 fluorescent tubes and compact fluorescent lamps. These ballasts have features such as superior dimming of 1 to 100% and intelligent lamp detection.
There are several installation advantages that modern equipment has over the old style control gear. A modern electronic ballast does not require an external starter because ignition voltage will be generated internally. There is also no need for a remote capacitor to be wired into the luminaire wiring circuit. Without these two components the circuitry is simplified making installation faster and easier.
The latest electronic gear from Companies like Tridonic Atco and Osram Quicktronic, will provide savings of about 25% on power consumption when compared with older control gear. It will also protect fluorescent lamps by preheating their electrodes and extending their life. Preheating also enables fluorescent lamps to be frequently switched on/off throughout their lifetime. This can be done without damaging the lamp or the ballast and therefore reduces the need for maintenance work.
