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.

Good service
Ordered halogen bulbs. They were out of stock but we were kept informed by the seller and asked us if we were happy to wait for stock to come in. Did not have to wait long and when the bulbs arrived they were safely packaged. Would use BLT Direct again and recommend to friends.
