cooker hood bulbs ..energy saving?

If the lamps in the cooker hood are enclosed, I think that you will find that energy saving bulbs(the CFL type)are not intended for use in an enclosed fitting. Also, I have my doubts whether they would be small enough to fit in the space taken by the lamp that you linked to.
Have a look here. It describes the risk of overheating in an enclosed situation.http://sound.westhost.com/articles/i...scent.htm#norm

Also this, maybe they are small enough as long as they are not enclosed. http://www.bltdirect.com/products.ph...ylight+Lam ps <

You misunderstand me. The problem is that CFL lights get hot when in a confined space. This affects their electronics. The 40w tungsten obviously generates heat but the enclosure is designed for this. My second link appeared to show an mes energy saver light which did not look very large. The first link gives a big no no to enclosing CFL's.

But other product listings i've just seen for tungsten cooker hood bulbs describe them as vibration proof..so that i think is likely to be the biggest issue. [....]
As always it seems that what i'm after is a product that doesn't yet exist (or at least so rare i can't find it!!).

I've been using a 9w SES energy saver candle bulb in place of the 40W tungsten in my cooker hood for over a year and it's still going, whereas the tungsten bulbs failed quite regularly

It's a cooker hood so not exactly an extreme environment! If you can find a bulb which fits, try it.

Same as message 6, I replaced the two x 40W bulbs with 2 x energy savers a few months ago and no problems at all, now only use 18W instead of 80W :j

Those bulbs you are using are VERY expensive! Is there not at least room for ordinary candle ones?

If you decide to go for energy savers, you can get reasonably priced SES candle/compact ones from Tesco and Ikea amongst others.

Also LED bulbs in an enclosed space is not good because these have to be kept cool for all the electronics to work so WOuld not be a good idea to enclose them. If you look up info about LED bulbs the big ones for main centre lights have heat sinks and fans in them to keep them cool

Same here, replaced the incandescent lamps in the cooker hood for compact fluorescent 9w each. Have been running for about a year or so now.

LEDs arent compact fluorescent. Sometimes the terminology gets mixed up.;)

I think people are going overboard about energy saving bulbs. How long will the cooker hood bulbs be on, 1 hour a day at most?

80 times 365 = 30 kWh which costs roughly £3 in electricity a year.

And probably a lot less than that, I only have mine on when I am actually standing at the cooker cooking.

How much will replacement energy saving bulbs cost to buy? A lot more than £3.00

I've been experimenting with this very thing of late as we sell a few hood and oven bulbs!

If anyone wants the URL just Google "UK Whitegoods" but I don't want to be spamming.

Basically there are two flavours of lighting used in most all appliances, standard incandescent bulbs and halogen bulbs and, with good reason it would appear.

The CFL replacements do have a tendency to overheat and pop when used in a hood, they are utterly useless for an oven or fridge as, in a fridge you want instant bright light when you open the door, not have to wait for the lamp to heat up. In the oven, well they melt.

In a hood they can work but it very much depends on the design of the hood, where the lamps are and also how much and what sort of cooking you. Oh and, how long you run them for. Running any bulbs for extended periods in a hood is not recommended, it often leads to a failure in the switch as it gets too hot.

LED bulbs are the same although they are starting to be used in fridges now, Liebherr use them on a number of models now.

They are not suitable for hoods in the main as the so-called drop in replacements have electronics in them that have the same issues as CFL lamps but they do need to dissipate heat a bit better in my experience. If they cannot dissipate the heat they blow, sometimes quite spectacularly and it's a lot of money to take a punt on so, since I've tried it in a number of hoods, trust me when I tell you not to bother.

The other issue with LED lamps in hoods is that, where you have G4 capsule bulbs, like this type, you can use the new drop in replacements but, they're not as bright by a long way I've found, can blow up as they're often cheap rubbish from China and thy can blow as they are not using a pukka LED driver. They say you can use a normal transformer but don't believe it, if you hook them up to one they are liable to overheating and premature failure.

The lesson learnt by all this tomfoolery with LED and CFL is, don't bother just fit what's already there.

To the OPN's problem of bulbs blowing early, there can be any number of reasons for it but, you will often find that the cheap and nasty bulbs do that but it can also be caused by faulty lampholders or by a faulty switch.
