Hi,

This lamp is a prototype I designed. It has an internal timer which can be set to a desired time period, After this time period the lamp automatically switches off.

To have a timer that reflects the cost of the electricity used would mean a 5 pence coin would light a standard 60 watt lightbulb for 9 hours (approx). Using an energy saving or LED lightbulb (I will be using one of these two types) would extend the length of the lamp being switched on dramatically. It’s important to not only look at the financial costs of running a bulb constantly when not needed, but also the environmental costs.

I am currently working with a manufacturer and will be launching the final product soon.

Trouble is my son’s reading lamp is a 0.7W LED unit – it barely registers on meters!

Oh, I didn’t know it was a switch – I thought it was more like a parking meter – a coin turns it on for a half hour or something…

The coin just acts like a switch? Dumb…

Actually, I think i makes the incentive to leave the lights one all the time. You have to pay to turn the lights on, not keep them on. You kids wont want to pay all the time, so they’ll toss a quarter in once, and leave it one.
