bulbs

[vickyvcool]

can someone tell me about bulbs whose intensity can be controlled using regulator?

Almost any sort can.

Normal LV incandescent - no problem. Dimmer may need to be derated (i.e. you need a bigger one) for halogen lamps.

Normal ELV incandescent - no problem, provided the transformer is dimmable, and the dimmer is suitable for transfomers, and the type of dimming is compatible between the two.

Fluorescents - generally not dimmable without special control gear which ordinary domestic fluorescents and compact fluorescents (e.g. low-energy replacement lamps) do not have.
