Bulb Help!
16 Answers
My 60w Asda ceiling bulb has just blown and I would like to get an energy saving one. Thing is, the 60w was too dim. What type should I get which is LED but still safe for the type of light it is? ie- won’t blow the system or set on fire?

For more on marking an answer as the "Best Answer", please visit our FAQ.15w is a rough equivalent led for 60 watt incandescent. If you remember that it is aboul a 4 to 1 ratio you can divide the wattage by 4 to give a rough conversion. Because led bulbs use so much less power you can go much higher with the luminence. I would think that you can go up to a 20 or 30 if you want it very bright. The main think to get right is the fitting. Note whether it is bayonet or screw fixing and get the right size for which one . There are 2 bayonet sizes and even more screw fix sizes.
If you put a 20watt led in it will double the lumens(brightness) of the old 60watt. Handy reference chart below.

Good stuff from the others, Scarlet, but I'm not quite so sure about Togo's ration.
In my experience, a 7W LED is roughly equivalent to a 60W incandescent. This does depend though on having the best quality LEDs.
It's quite right that Lumens are the real governing factor here, but I fear that 15W LED would be way over the top. (Unless it was a cheapie, in which case it probably won't have a long life.)
8-900 lumens is about right (should be around 7W LED.)
There used to be cool or warm, but now good LEDs can come in 3 tones.
You probably have either Bayonet (BC), Edison Screw (ES) or GU10
GU10............

Can you tell us which you have?

>>> 15w is a rough equivalent led for 60 watt incandescent
Not according this (from a company that sells nothing but light bulbs), it isn't!

I don't think that you'd need to worry about that. Assuming that you opted for a 13W LED bulb, and that the lighting circuit is protected by a 6A circuit breaker (as is usual in modern homes), you could plug in 100 of those bulbs without overloading the circuit!

//For example, if you need to replace a 60-watt incandescent bulb with an LED bulb, then divide 60 watts by 5 to get 12 watts – that will be a good estimate. But efficacy varies wildly from manufacturer to manufacturer, so it’s best to check the Lighting Facts label and try to match lumens//
In the link supplied chaps ... as I was saying. Get the right fitting or all else is pointless. Also beware that if the light is on a dimmer switch you may have to change the switch for it to work. There is no danger, as such, in fitting an led lamp(for ginge) to a dimmer used with the old "hot glow" bulbs but I would not like to chance an older type buld through an led dimmer switch. I have changed every fitting in the house to operate lred lights and that includes the fluorescent fitting. Taking the Fluorescent fitting down and replacing it, in the kitchen, would have been a bit involved and may have needed plaster and paint. So I stripped it down cleaned it till it was pristine again and put an led tube in. Great move too. As Lady said it is great in the kitchen because there are no shadows or shady areas on the worktops, or over the sink. So I am told.:))
