Introduction to Smart Lighting : B22 LED bulbs
What
is a B22 LED bulb?
B22 bulbs have the classic bayonet base
fitting, which features two ‘mounts’ on either side of the bulb.
This is also known as a ‘standard’ bayonet
fitting and is the most common in the UK. Make sure you don’t get confused with
B15 bayonet fittings that are smaller and less common.
LED B22 bulbs are identical to the B22
bulbs you’re used to buying in the shop. The main differences to consider is
the energy saving potential, longevity and light quality of LED B22s.
They will reduce energy consumption by up
to 90%, which is massive when you consider lighting is the second highest
consumer of energy in your home.
Add to that a 25,000 lifespan that is 20
times longer than your standard incandescent or halogen B22, and you can see
the real value for money. Smart LightsUK
What
wattage do I need?
Think wattage is a sure-fire measurement of
brightness? Well, think again…
When it comes measuring the level of
brightness in a B22 LED, you need to consider ‘lumen’ value.
For example, a 4.5W B22 LED bulb with 350
lumens will produce a brightness similar to that of a 50W halogen B22. The
important difference is that the LED will consume a tenth of the energy.
It’s also worth noting how beam angle
effects brightness. A narrower beam angle (of 45° or less) produces a more
concentrated, and thus brighter, light.
At Homeflow we specify the rough
wattage-lumen equivalents to help you make a decision.
Which
colour light is best for me?
B22 LED bulbs come in different colours
too. These colours are measured in Kelvins. The lower the Kelvin, the warmer
the light, the higher the Kelvin, the cooler the light.
You can choose from Cool White, Warm White
and Daylight colours. Where you use these colours is entirely up to you. If you
want an idea, many customers use Warm White for cosy living areas, Cool White
for bathrooms, while Daylight offers a happy medium.

Will
I need an electrician?
Nope. You can pop B22 LED bulbs into any
standard bayonet fitting.
Can
I purchase dimmable B22s?
You can indeed. They only cost a little
extra and the best bit is that they can be used with most 3rd party dimmer
switches. However, for optimum performance, we advise trailing edge and
inductive dimmer switches. SMART LEDBULB DIMMABLE B22
What
beam angle do I need?
The beam angle is basically the width of
the beam of light that comes from the bulb. It’s measured in degrees and a
wider beam angle covers more space with light.
Your choice of beam angle, like colour
variant, is completely down to you. As a guide, we’d advise using wider beam
angles in living spaces where many people are gathered round. Narrow beam
angles, on the other hand, are often used for decorative purposes or areas
where you need focus.
How
much will a B22 cost me?
First off, there’s a myth that LED bulbs
are expensive – this is a massive misconception. Yes, the initial cost is
higher than that of a halogen, CFL or incandescent, but you’ll get that money
back on your energy bills quickly. Not to mention LEDs last longer (20 times
longer in fact), which means you won’t be replacing them anywhere nearly as
often.
