Light bulbs for 'touch-reactive' lamps - is there a generic name?

[CraigRevelPan]

The bulb in dd's touch lamp has gone - the sort of bulb that will glow 'low-med-high' on each touch. Standard bulbs only glow at high level Is there a generic name for these bulbs so I can check out which shops sell them?

tia.

There should be a code on top of the bulb - google it and you'll find loads :)

ooh WMMC - bulb has gone to the great bulb place in the sky. Is it that specific? Crumbs.

Bugger. Try looking on the bottom there may be a sticker with guidance or a brand name of the lamp so you can identify it online.

It will be one of these though

Ah! it will be the 25watt triple life. Will check if it's screw or bayonet.

Thank you v. v. much. You were wafted from heaven. Or Grimsby, may be.. Thanks.
