Really Warm LED Bulb To Replace Bayonet 60w And 100w?

The elusive perfect bulb - a quest close to my own heart!

Ok, first things first: if you want a warm light you need to choose something with a Kelvin count of 2700 or less. Any higher than this and it will be a colder light.

Next, choose the light output you want. As a general rule of thumb most people know that a 100w bulb is bright and suitable for a main light, that a 60w bulb is suitable in a lamp, and 25w bulb works where we want soft and gentle light. LED bulbs use about 10% of the energy of traditional bulbs – so 10w will give you the equivalent light output of an old 100w bulb, 6w of a 60w bulb, and so on.

This one, from Ikea (again just a personal suggestion) might suit your purposes. If not, armed with the information above, you should be able to get what you need.

Incidentally, if your fitting is a bayonet fitting, you can easily buy converters on places like eBay that allow you to use a screw fitting in your bayonet lampholder. In this case you would need a B22 to a E27 converter.

Is it possible to replace GU3 halogen bulbs (the sort with two thin pins at the back) with LED lights, without ripping out the entire system? I have asked this question before, and was told no, but technology is changing all the time.

Yes, it is possible. The GU tells us that the base has a bi-pin cap, meaning that it has two pins and the number, the distance between the pins - in your case 3mm.

So it is simply a matter of finding an LED replacement bulb that meets that specification.

I had a quick look online and it is possible to source them as more and more LED bulbs are now being introduced. Remember, these are generally low voltage bulbs so you will need to ensure that they are compatible with your system. See my other answers (and guide below) about replacing low voltage lighting.

When you are replacing very specific bulbs, see you if you can get an 'exact match' or 'perfect fit' labeled bulb so that you know they will fit into the existing aperture.
