Glossary

Ballast

An Electrical Ballast is a device that is used to maintain the current in a circuit. Inductive ballasts are used with Fluorescent Tubes, Compact Fluorescents, Metal Halide, Sodium and Mercury light bulbs.


Electronic Transformer

An electronic transformer is used to reduce mains voltage to a suitable voltage for halogen light bulbs (Not to be confused with LED Drivers). When selecting a transformer it is important to ensure the max wattage is not exceeded by the total wattage consumed by the light bulbs.

Please Note: It is not recommended to "max" out transformers.

IE 5no. lamps x 10 watts each = 50 watts therefore a 60 watt (60VA) transformer would be acceptable, however if you had 6 lamps a 60 watt transformer would be "maxed" out. In this case we would then recommend a 105 watt (105VA) model.


Ballast Factor (BF)

In simple terms Ballast Factor is the percentage of the lamps lumens that the ballast is expected to emit. For example if a ballast had a ballast factor of 0.98 it would be emitting 98% of the lamps rated lumens.


Electromagnetic Ballast

The original type of ballast, the electromagnetic ballast was introduced with the first iteration of fluorescent lamps.

First Dealings with BLT
There proved to be problems with my order but this does not worry me. My concern is how a company deals with problems that will invariably arise. BLT could not have been more helpful and consulted me and offered further help and advice at each stage.
