tube light

[cecil39]

would like to hear from anyone that has a tube light in a bathroom without a window, I don't mean a fluorescent tube but one of those that magnifies daylight, I think it might save on electricity as we wouldn't have to switch on every time we go in daylight, are they as good as they sound?

There is some info about them here

Lets see now - say 2 hours per day with the light on, perhaps a 60W conventional bulb (one of those greedy ones that Ed Milliband wants us to throw away) - that's 42kWh per year.
A kWh costs about 10p, so that's about £4.20p per annum by my reckoning. Less if you use a low energy one.
Cost of a Sun Tube, including installation - perhaps £600 as a wild guess.
Still think it could be worth it on those grounds?

thanks for your help everyone, I will have to enquire as to how much one of these things costs to supply and fit, unlike buildersmate I would never be able to do the math re power saved, but all very interesting.

I've looked into this for myself; (for a kitchen)

"Suntile" around £130 each (depending on your roof tile/flat roof) includes a 345mm long duct ("Suntube)
Short (900mm) "Suntube" around £75
Long (800mm) "Suntube" around £110.

Prices including VAT and shipping.

Fitting cost, at least double material cost.
