Will my current dimmer work with LED bulbs?

When using LED bulbs with dimmers that have been produced for conventional lamps - there can be a mismatch in technology, that can cause issues like flickering; Your existing dimmer may have been designed to dim high-power circuits, whereas LED lamps are low-power products. You should change your existing dimmer for a dimmer designed to work with LED. 

  1. Are you using a non-dimmable lamp with a dimming circuit?
    Using a non-dimmable LED bulb in a dimming circuit can cause damage to the LED bulb and/ or dimming circuit. Integral packaging and lamps are marked with text or an icon as non-dimmable or dimmable.
  2. Your existing dimmer switch may be incompatible with the dimmable LED lamp you have purchased. A common reason is that the LED bulb power load is below the minimum load required by the dimmer. e.g a dimming circuit for a 60W bulb may be installed with a dimmer with a minimum load of 25W. A replacement LED bulb may only be 5-6W falling below the minimum level required by the dimmer.
  3. Incompatible transformer.  If you are using low-voltage lamps (MR16 12V Spotlight) your existing transformer may not be compatible with your LED lamp. 

We would advise you to use a qualified electrician to make any changes to your electrical circuits.

How long will an LED lamp last?

The lifetime of a LED lamp is defined in hours. As with all types of lamp, the light output very slowly fades over time. LED lamps do not generally burnout they will still perform after their rated hours  e.g 25,000 hours.

The lifetime is the figure stated when the light output is predicted to drop by a significant amount of the original light output where you may consider a replacement, this is partly due the the slow aging of the parts of the lamps such as refractors and other components.  External factors such as heat, humidity, switching cycles and power supply will affect the lifetime of an LED lamp.

The table below gives an indication and comparison with filament and CFL lamps on how many years a LED lamp rated at 25,000 hours will operate.

As you can see a LED lamp will last over 22 years (at 3 hours per day) against a filament lamp of less than a year and a CFL of just over 9 years. 

The longer life of LED means less time spent on lamp changes (important for hard-to-get-at areas) . Also it's great for the enviroment with less lamps, packaging and transport energy being used. 

lifetime in Years LED 25,000hrs Filament 1,000hrs CFL 10,000hrs
Hrs/Day Years Years Years
3 22.8   0.9 9.1
6 11.4 0.4 4.5
9 7.6 0.3 3.0
12 5.7 0.2 2.2
24 2.9 0.1 1.1

Switching cycles

All lamps including LED have a number of switching cycles. This is the minimum number of times the bulb can be switched ON and OFF before failure in normal use, lamps may go on to last longer.   For a typical value of 12,500 the lamp can be switched ON and OFF once a day for a minimum of 34 years!  (Environmental factors such as temperature can affect the value). In general, LED lamps for home or office use are not designed to be switched ON and OFF rapidly.








lntegral LED lamps willl fit most existing light fixtures.

Integral LED lamps can be used as direct replacements for most of your existing lamps. It's as quick and easy as replacing a conventional bulb.

All the common base types are available in the Integral range, we are very retro-fit friendly.

Use our product search to find the ideal product

The Integral LED team have chosen our LED lamps very carefully, so that they are physically very close in physical dimensions to the traditional bulb shapes that they replace. They should blend in with your light fittings better than some CFL energy saving bulbs that can protrude and can look unsightly.

What do "Warm White and "Cool White" mean?

With LED lighting, especially spotlights you may have the option to choose the "light colour", known as " (Correlated) Colour Temperature  (CCT) ". Two examples are "Warm White" and "Cool White". There are no rules - the choice is about personal preference and use. CCT is expressed in Kelvin (K).

  • A Warm White Integral LED lamp will provide a traditional yellowish colour light, similar to conventional bulbs. This is the most popular choice.  (2700-3000K)
  • A Cool White Integral LED lamp will provide a modern, clean, bright light, that is slightly blue in colour.(4000-5000K)

Fitting a LED bulb is like fitting any other bulb.

Fitting an LED bulb is the same as fitting any other bulb – but you will have to do it less often!

Before you change a bulb please ensure you have a similar LED replacement with the same base fitting, shape and light output.

Find out how to select an LED lamp.

Before changing or inspecting a bulb always turn OFF the power at the mains.  Please take the necessary precautions if working at height.  Wait for the current lamp to cool if required. Carefully remove the current lamp making sure you keep safe any clips or fittings. Fit the new LED lamp and switch the power ON and think about the energy savings you are making when compared to a conventional lighting. Sometimes a new light source may take a couple of days to get used to. 

Lamps should be changed by a competent person. Please contact a qualified electrician if in doubt or to make any additions or changes to your circuit.

Dispose of old bulbs responsibly, especially CFL lamps that may contain mercury. Bulbs are not normally disposed of into the normal domestic or commercial waste stream, if in doubt check with your local authority.

How does the Integral Auto Sensor lamp work?

The Integral Auto Sensor lamps are available in two fittings:

Large Bayonet (B22)

Large Screw (E27)

The lamp will switch ON at around dusk when the daylight intensity level drops to less than 80Lux +/- 30% it will switch OFF at dawn when the daylight intensity level reaches 300Lux +/- 30%. On overcast, stormy or dull days the light may stay on a bit longer. On average there will be around 12 hours of darkness over a year - Using a LED lamp will lead to significant savings on energy when compared to a conventional lamp. Ideal for turning your existing external light fitting into switching ON and OFF automatically - just by changing a bulb.

  • The lamp has two sensors to give 360 degree coverage – make sure that at least one sensor can “see” daylight
  • The auto sensor lamp has been designed to work in suitable external clear glass or plastic fittings - some shades may affect the operation of the lamp.
  • There is no warm up time as the lamp is instant on
  • The lamp has been designed for suitable outdoor lamp fittings such as porches
  • Once the lamp is safely installed, make sure the power is continuously applied to the lamp  
  • The lamp has been designed to see natural daylight and will not work indoors with artificial light
  • The lamp does not have a PIR sensor to sense movement
  • The lamp is non-dimmable so cannot be used with a dimmer switch
  • The sensitivity of the lamp to daylight is fixed and cannot be adjusted
  • Functionality may be affected if your fitting is on a PIR or other detection circuit
  • For the lamp to function if must be powered. The light switch must be on the ON position

General Lighting

Integral LED products are instant on - there is no warm up time.

Integral LED lamps are "Instant On", they light up instantly, just like conventional bulbs. They have no annoying warm-up period unlike most CFL bulbs.  With LED lamps you enjoy a better performance whilst saving money.

Integral LED products do NOT contain mercury - unlike some CFLs

LED lighting does not need mercury to be used as part of the lighting process, unlike some CFL bulbs. Integral LED lamps do not contain mercury or any other hazardous chemicals or materials.

Can I use dimmable LED bulbs / lamps with just an On/Off switch (without a dimmer) ?

Yes - This is a good idea if you are thinking of upgrading to a dimmer in the future. Ensure you buy a LED compatible dimmer. We recommend the VARILIGHT range of LED dimmers. Non-dimmable bulbs should NOT be used with a dimmer.


What should I consider when buying an LED Strip ?
LED strips make a great addition to any domestic or commercial environment. They can change the mood and look of a space instantly and are very energy efficient. The possibilities are endless so the requirement for each lighting project will be different. It is worth taking some time to plan your project for the desired effect before removing the backing tape on the LED strip.  You also need to consider if the LED strip will in temporary contact with water.
The specification, length, mounting position and distance from an object determines the appearance of a lit LED strip. You will also need to consider the placement, protection and concealment; of the 12V LED driver and wires, and the power switch to turn the LED strip ON and OFF.
We recommend that you test the strip by temporarily holding the LED strip in place by using a suitable tape, such as masking tape. Safely connect the power supply - you can then carefully move the strip to try different angles and positions to gain the desired illumination effect and position. Check for light spots, reflections and shadows.
Please consider the surface you are applying the LED strip to; the surface should be stable, clean and smooth. On removal of a fixed LED strip - damage to paint, wallpaper or other substrates may occur. Take care in measuring the length required before cutting the strip, take into account the space required for the connector.
You may also need to use a spirit level, plumb line or other guide

What type of LED driver should I use with LED Strips?


Do NOT connect the LED strip directly to the mains power supply - A LED driver must be installed.

Integral LED Drivers have been designed to compliment our Integral LED strips

Integral LED strips operate with a 12V direct current constant-voltage power supply known as a LED driver. (Avoid using a constant-current driver)  Drivers are sold separately and are available in varying wattage outputs. The specification of the driver required will depend on the total power requirement of the connected strip(s). 

The power output of the driver (wattage rating) must be at least 10% higher than the total required wattage of the strip(s) being powered. For example, if you are installing 5 LED strips of 1M each and the power requirement of each 1M strip is 3W/metre – the total power requirement is 15W. The power rating of the driver should be a least 10% above 15W i.e. A minimum of 17W.  In this case our Integral 20W LED driver would be the ideal choice.  The "related" product on the product page will specify the correct LED driver for a particular LED strip's total length. (if you are using only part of a LED strip a lower powered LED driver may be applicable)
