Replacing your current bulb with LED is as easy as well, changing a bulb. Integral LED produces a range of retrofit lamps that will fit right into your existing lamp socket so you can begin to save money immediately. In most cases you can retrofit a like-for-like LED bulb with the same base fitting, similar shape and light output. When choosing an LED lamp there are a couple of extra choices to make on dimming and light colour.

SHAPE

Depending on the fitting, you would normally replace your bulb with an LED bulb of the same shape, Click on a link to see all products that match that shape.

  • Classic Globe - One of the most popular types also known an "A / A60 type" or GLS lamp. Used in ceiling fittings and in table, wall and floor lamps
  • Mini Globe - Fitted in table, wall and floor lamps, also known as "G or P45" type"
  • Candle - Ideal for chandeliers and and wall lamps, also known as "C or B35 type". There is a choice of clear or frosted (opal)
  • Spotlight - PAR16 also for ceiling fittings

Some LED bulbs are available in a frosted (opaque) or clear finish. 

BASE 

A lamp with the correct fitting base needs to be selected. Bases are not interchangeable. Click on a link to see all products that match that fitting.

  • B22 - Popular large "Bayonet" - push-and-twist, 22mm in diameter - found in many ceiling fittings in the UK 
  • B15 - Small "Bayonet" - push-and-twist, 15mm in diameter - not as common as B22, but the fitting is used in selected countries around the world
  • E27 - Edison Screw (ES), 27mm in diameter - widely used in ceiling, table, wall and floor lamps.
  • E14 - Small Edison Screw (SES), 14 mm in diameter - many uses including  table, wall and lamps.
  • GU10 - Bi-pins (10mm apart) twist-and-lock fitting found on 240V spotlights - Be careful not to confuse this with the low-voltage (12V) MR16 push-fit spotlight fitting 
  • MR16 - This is a bi-pin push-fit spot lamp used in 12V low-voltage spotlights circuits - that includes a transformer and possibly a dimmer.  There are some possible difficulties in replacing existing MR16 lamps. As older technology transformers (240V to 12V) and dimmer switches have to be taken into consideration. Transformers and/or dimmers switches may need to be replaced with LED compatible versions. An alternative is to replace the MR16 lamp holder with a GU10 (240V) lamp holder and remove  the transformer and use GU10 lamps. Any changes to your circuit should be carried out by a qualified electrician.
  • G4 - Sometimes called bi-pin capsules. These are small lamps with two pins that run with 12V transformers.  G4 are found in light fittings and cooker hoods.
  • G9  - These are also called capsules. These small lamps have two looped pins and run on 240V. G9 are found in light fittings and spot lamps.  

DIMMING

Making the correct choice is very important. Using a non-dimmable lamp with a dimming circuit can damage the lamp and or the dimming circuit. Click on a link to see all products that match.

  • Dimmable - with compatible dimmers. Can be used with non-dimmable circuits.
  • Non-Dimmable - Must be used with a non-dimmable circuit only. Installing non-dimmable lamps in a dimmable circuit may cause issues even if you don't intend to use the dimmer.

Dimming LEDs with installed dimmers designed for higher-load filament lamps can present issues in some cases.

LIGHT COLOUR

The choice is a matter of preference and use. Light colour is denoted in Kelvin (K). Click on a link to see all products that match a colour temperature.

  • Warm/Warm White - 2700K to 3000K - If you prefer yellowish light closer to traditional lamps. Warm white is the most popular choice for the home. 2700K is close to a filament lamp
  • White/Cool White - 4000K to 5000K - If you like a clean, modern, blueish light, mainly used in commercial, retail, kitchens, bathrooms and contemporary areas. Mostly available as spotlights.

LIGHT OUTPUT

Measuring a light output by Watts no longer applies, as LED uses far fewer Watts to generate the same light output. For example a traditional lamp of 60W can be replaced by an LED lamp of only 6.5W. Lumens is a "new" way of denoting how much light is visible from a lamp. The higher the lumens the brighter the lamp will be.

Below is an approximate guide to help you decide on the lumen rating for your LED replacement lamp. (click on the "old wattage" to display the lamps available)

Old Watts Approx Lumens
25 W  230 - 270 lamp
35 W

250 - 280 spotlight

390 - 410 lamp

40 W 440 - 460 lamp
50 W 330 - 350 spotlight
60 W 800 - 850 lamp
75W 1000-1100 lamp
100W  1500 - 1600 lamp

Some common retrofit requests

I have 8 X 50W spotlights with push-and-twist GU10 in my modern kitchen that are non-dimmable. I like the bright, clean look of cool white. see option

I have 2  X  60W large globe bulbs with "large screw" fittings in my apartment's living room floor lamps without a dimmer. I prefer warm white.  see option

I need 6 X  25W candle lamps with a small screw fitting for my chandelier in my cottage that are dimmable. They have yellowish colour light. I want to choose between frosted or clear. see option

I need an equivalent bright led lamp that can replace my single 100W bulb that I have in my room. see option

I have an outside enclosed lamp fitting near my front door. It uses a large screw standard type bulb. I would like an LED lamp to come on automatically at night and off in the morning. see option
