Long lasting emergency lights?

[tim...]

seems a pointless move, as for the majority of uses the cost of installation is likely to swamp the unit price

So, who is going to make incandescent 'bulbs' just for emergency lights?

[Andy Burns]

I though (pre-LED) they mainly used 12" T5 tubes?

[charles]

I've fitted some with lamps, but even small tubes are going out of production,

I had a very old one that used 2 x torch bulbs. Don't remember the rating.

I meant deliberately putting smaller batteries in

And one of the things about these bespoke LED products is that they tend to be sealed for life

which means that in 25 years when the bulbs die, you have to get the electrician in to do a complete re-install

So much better if it had standard fittings and you manually put LED bulbs in there yourself

[tim...]

replacement LEDs with the same fitting are usually available

[charles]

But they are standard fittings - modern standards

[charles]

Plenty for large fluorescents - I have a few here, but haven't seen any for the small tubes.

for illumination, or ... ?
