FAQ:
Q: Are ferromagnetic Transformers in downlight fittings any good?
A: Many of the older downlight fittings use ferromagnetic (iron core) transformers. While simple, they are inefficient compared to modern electronic replacements. To determine the extent of losses in these transformers I performed some simple testing.
Q: What size transformer do I need for a halogen downlight?
A: Transformers and LED downlights MR16 halogen downlights require a transformer for each globe. Most transformers/drivers installed with halogen downlights are rated as either 50 or 60 watts (or VA).
Q: Do you need a special transformer for led downlights?
A: All LED bulbs require a ‘driver’ (a special type of transformer) to work properly. Mains voltage LEDs (such as GU10 and B22 bulbs) have the driver built in to the bulb. If you are replacing existing incandescent 12V bulbs you will need to replace the transformer with a special LED driver. Also, can you replace normal downlights with LED?
Q: Where can I buy a transformer for lighting?
A: Lighting Transformers | Lighting | Screwfix.com Buy Lighting Transformers at Screwfix.com. Converts voltage for light fittings. Various types. Buy online and collect in store in as little as 1 minute.
