Lightbulb help.
 
Im looking for advice on lightbulbs.

Lastnight the LED bulb in my bedroom decided to pack in, it was a 43watt bulb.

Today to replace it thinking the lampshade was max of 100watt where its 60watt i bought some halogen classic bulbs to replace it which are 100watt = 129watt.

Now i know the reason they put the max wattage on lampshades is because of heat, my question is will it be ok to put a new bulb with existing lampshade? The new bulbs dont give out nearly as much heat as the old bulbs this is where im confused and asking.

Thanks.

If the bulb wattage is too high the lampshade could melt if it's made from a plastic material, or potentially catch fire if made from material.

I would get a different lampshade.

I'd get replacement LED bulbs. Minimal heat, high lumens (brightness) less power consumption.

I agree, you can buy LED light bulbs up to 150 watt equivalent now with consumption of 10 Watt.

OK thanks guys.

I would suspect that the 129W value is the light equivelent of a standard bulb compared to the halogen. The 100W will be the heat equivelent.

However I'm steadily replacing all the conventional bulbs in our place with LEDs as they fail. If you need something that looks like a conventional bulb, especially in fitments that need that sparkley effect then consider LED filament bulbs. These are available in a number of styles including antique immitations like this:

My LED bulb average 60 watt is not nearly as bright as my older type

My 11 watt LED bulbs rated A+ are far, far brighter than old fashioned type 60 watts, but they are expensive. Let's hope they last as long as they claim.

Mine is just Pifco, Luman =22W. AC W3 bulb size 60" The bulb sits under the glass shade facing upward to it will not take a larger bulb, it is not as bright as I would like , ;)

The figure of merit for any lightbulb, irrespective of technology, is the Lumen. As a guide a standard 100W filament bulb emits about 1600 Lumens. This is the total light output of the bulb.

Scale as appropriate and select your LED bulb accordingly.

I've had some really good bulbs from Lidl under the Livarno Lux brand. The Narrow beam GU10 dimmable reflector ones are rated at 5W but are a perfect replacement in colour, brightness and beam for 50W halogens. These have 3 LEDs with colimating lenses in front.

Home Bargains have been selling GLS style LED lamps for a while now. I have all my chillie and strawberry seedlings under the 100w equiv ones, and the whole house is now bright and cheery.

9w (60w equiv) 806 lumens daylight (6500K) £1.59

12w (100w equiv) 1500 lumens daylight (6500K) £2.99

They sell both bayonet and Edison screw versions.

I have noticed that the "warm white" lamps have a much lower lumens rating that the "daylight" ones. I wouldn't buy them anyway, who wants yellow light in their homes (apart for those that yearn back to gas lighting?).

Whilst we are on the topic of bulbs and there seems to be a few knowledgeable people here.....I have one of these which uses a 300W dim-able, giant edison screw, incandescent bulb.
Due to the EU rules, I'm having a hard time sourcing a replacement 300W dim-able incandescent and the LEDs that I've found aren't dim-able or 300W.
Can anyone point me in the right direction? :)

Wilko sell dimable LEDs not as high as that though.

Try ebay or amazon?
