Bulb replacement

[cascade]

Might seem obvious to you but are all secuirty light bulbs ( ie cheap ones from band q etc ) the same size?
Been told to get R7s ( whatever that means) and they should fit

R7s is the standard 118mm 500watt ( sometimes 300watt) halogen tube size and fitting. the 150watt are smaller, forget the code for them.

I think the R7's are only 80 - 100 watts for the B&Q security lights, i believe you can get an LED version, though it will cost considerably more than a standard bulb.
Just take the old bulb out to find what wattage it is, easiest thing to do.

 

[Taylortwocities]

R7S/RX7S covers a wide range of lamp wattages (I have seen 60watt to 1500watt) and lengths - 78, 117 and 254mm being typical standard lengths.

There's a range here BLT Direct Search
