LED Bulb

All types of LED bulb are now available to suit standard home fixings, including screw and bayonet. Here’s a quick guide to the different types of LED bulb available.

1.  E27 (Edison Screw)

E27 bulbs are the most popular around. They’re also known as ‘Edison Screw’ bulbs or simply ‘ES’.They’re used widely across the UK and also over the Atlantic in the US.

They measure 27mm, which is the same as a halogen or incandescent E27, so you can simply pop an LED E27 into an existing E27 fitting – it’s completely hassle-free.


2.  E14 (Small Edison Screw)

The screw on an E14 bulb is identical to an E27 but for one thing: it’s smaller, measuring just 14mm in diameter, which is why they’re often used in small fittings for decorative or purely practical purposes – such as chandeliers and appliances


3.  B22(Bayonet)

The B22, or Bayonet, light bulb fitting. It measures 22mm in diameter and is often found hidden behind lamps and lamp shades.


4.  B15 (Small Bayonet)

A smaller alternative to the large B22 bulb, the B15 bulb measures just 15mm in diameter to accommodate smaller fittings.


5.  R50

R50 bulbs – also known as reflector bulbs – feature an E14 Edison screw fitting, but are shaped differently at the top to accommodate different lamp fixtures and uses.


6.  R63

The R63 is a reflector bulbdesigned with a protruding bulb-cap to accommodate different lighting fixtures, but features a standard E27 Edison base fitting.


7.  PAR38

The PAR38 is a bulb that kicks-out a lot of lumens (brightness). It comes with a screw fitting and is often used for workshops, security and commercial lighting.

LED lighting is ever-evolving and getting smarter too.
