B22 LED bulbs are designed to be direct replacements for old incandescent and halogen bulbs that are known for being very low on the energy efficiency scale. The B22 LED bulbs are the most popular fitting out of E27 and B22 as they have the very common bayonet fitting. This means that B22 LED bulbs can be used to directly replace the standard bayonet light bulbs that you already use in the home without any need to change fittings or buy in new lamps and ceiling lights. Just simply remove your existing bulb as you normally would and then replace it with your new B22 LED bulb for an instant fit without any hassle.
The B22 LED bulbs come in a variety of different shapes to match your existing bulbs and they also emulate roughly the same light levels as most traditional bulbs. For example, you can easily get hold of B22 LED bulbs that give out the equivalent light to 25 watt incandescent bulb, a 35 watt bulb and a 50 watt bulb. The different here though is that the B22 LED bulb will produce the same amount of light but with a lot less power. This is because LED bulbs do not lose much of their energy through heat, whereas incandescent bulbs lose as much as 80% or in some cases, 90% of their energy as heat rather than light. This is why a light bulb that has been on for a while is so hot to the touch or why you can even feel the heat coming off of strong halogen spotlights. This heat is an undesired byproduct (as it is light that you are looking from a bulb after all!) but due to the use of filaments and the way that light is produced, the majority of energy that goes into an incandescent bulb is actually wasted in heat.
So, if we take the B22 LED bulbs of the equivalent light that we just mentioned, such as the 25 watt bulbs, the 35 watt bulb and the 50 watt bulb, you will actually find the B22 LED bulbs using around just 10% of the power. So, to get the equivalent amount of light from a LED bulb as you would get from a standard 25 watt incandescent bulb, you would need just a 1.8 watt B22 LED bulb. To get the equivalent amount of light as a 35 watt incandescent bulb, you would need a B22 LED bulb that uses just 3 watts and even to get the equivalent amount of light as that emitted from a 50 watt incandescent bulb, you would need just 5 watts from the B22 LED bulbs. This goes to show the huge energy savings that can be obtained by using these B22 LED bulbs and what makes them even more appealing is that they slot straight in to your existing lamps and light fittings as if they were just another standard incandescent bulbs.
