This might sound a daft question but I don`t like ignorantly messing with electricity/voltage/wattage.
Anyhow (clear my throat and risk looking daft) one of my xmas trees is fibre optic and the bulb seems to be broken. It needs a 20V 10W bulb but I can`t seem to find one in the shops. Would it be safe to put a 20V 20W bulb in? don`t want it blowing up or my house burning down ![]() Many thanks |

Is there a transformer (power brick) with the tree. It should have a sticker on it which says what output it can handle.

![]() ok (said sheepishly) it`s a 12V not 20V The sticker says Bulb: 12V 10W and rated voltage/wattage 12V 12W so i`m guessing that means that I can`t put a bulb higher than 12W in? |

Personally I wouldn't draw 20W from a transformer topping out at 12W, on something that is left unattended and switched on for a length of time. I'm no expert on what would happen, but my gut tells me it's not a good idea. Last edited by -Ralph-; 13-12-10 at 11:57 AM. |

If the transformer is only rated at 12VA, then I'd expect it to get rather hot with a 20W bulb. So I wouldn't recommend it.
Try taking the dead bulb down to a car parts shop (not Halfrauds) and see if they have a suitable replacement. You could also put a couple of photos of the bulb on here. Someone might be able to identify it for you. Keith |

Thanks Keith.. it`s the same sort of bulb as goes in a halogen spotlight and has 2 prongs. I think i`ll do as you suggest and try a car parts shop as there`s one nearby. I do have a 12V 20W halogen bulb but as you say I won`t risk it

We need a bit more information
Look on something like the CPC web site search for lamp bulbs, halogen and then low voltage. Try to identify it there. I assume it is going to be a capsule lamp bulb but you need to know exactly which fitting.

You need to measure the diameter of bulb. Mr16 ones tend to be 50mm, but I haven't seen any rated at 10w
Is it this, which would be about 35mm diameter?

Right Claire, its your lucky day.
Also, the wife has sent you a message on FB about another place she found, but i changed our bulb which was identical to that, got mine from screwfix. If you have a trade counter by you just take it in there otherwise you will have to order one which may get pricey. HTH |
