The halogen bulbs for our recessed ceiling spotlights have to be replaced quite often.
Could we be using the wrong transformer/bulb combinations? How would I find out? Does the number of bulbs attached to any one transformer influence the life-span of the bulbs or the transformer? Are these bulbs drop-in replaceable by LED bulbs?
Transformer output: 11.5V, 35-105W
Bulb specs: 12V, 30W
The situation: Due to their location in the room we have 2 bulbs connected to a transformer. We have a total of 6 transformers and 12 bulbs.
Please leave a comment if more specs are needed to answer this question, then I will try to look them up. NB: The grid voltage is extremely stable in our neighbourhood.
