FAQs

What is an LED light bulb?

A LED light bulb uses LEDs (Light Emitting Diodes) as a source of light. We believe that LED lights are the future for energy saving bulbs as they use much less power than halogen or fluorescent bulbs and last a lot longer too, therefore costing much less to run and replace.

What is the life span of a LED bulb?

Compared to halogen bulbs, LED lights have a much longer life cycle of up to 50,000 hours which works out as over 5 years if the bulb were on continuously. Therefore you may find when you switch your bulbs to LEDs you might not have to replace them again.

Most people don’t leave their lights on 24/7 so this will show you a more realistic life-span guide:

LED light bulbs have an average life-span of over 25000 hours, equating to:

  • 2.9 years (if kept on 24 hours per day)
  • 3.7 years (if used 18 hours per day)
  • 5.7 years (if used 12 hours per day)
  • 8.5 years (if used 8 hours per day)

Are LED lights a green lighting solution?

LED bulbs are the most eco-friendly lighting because LEDs operate at a much greater efficiency giving off very little heat and not wasting energy. Not only will this save you money on your lighting bills, but it also helps reduce your carbon footprint so switching to LED lighting is good for the environment as well as your wallet.

How hot do LED bulbs get?

LED bulbs do still get hot however they run much cooler than other types of lighting,because the heat is dissipated by metal heat sinks that remove the heat from the light source itself. This helps to maintain a long life span of the LED bulbs.

What quality of lighting do LED bulbs produce?

LED bulbs provide a very high quality of light output. The majority of our bulbs have the option of either warm white or cool white, some have other colour options too, but the colour you opt for is dependent on your preference. Not only is the light produced bright and great quality but LEDs do not require any warm up period unlike some halogen or fluorescent bulbs, when you switch them on they are 100% on. LED lights also do not flicker unlike standard bulbs. There are many benefits to switching to LED lighting and the cost of running them and quality of light produced are two of these.

Which LED bulbs do I need?

This depends entirely on your existing light fittings. We have a huge range of LED lighting options which spans a large selection of the most popular bulb types including G9, G4, MR11, GU16, MR16 etc.

If you are looking for a LED bulb to replace your standard bayonet bulb, you will require a B22.

If you are replacing Edison screw cap bulbs, the standard 27mm size is our LED E27 and the narrower 14mm size is our E14.

Make sure you get the correct size of bulb that is compatible with your existing fittings, check our product information details before you buy.

However, if you are confused as to which bulbs you are looking for, don’t hesitate to contact our lighting experts and we will endeavour to help you find the perfect replacements.

Do LED bulbs contain any toxic materials?

Unlike some other types of household lighting, LED lighting does not contain any toxic or harmful materials inside them. LEDs are a solid state lighting technology.

Do LED light bulbs need to warm up or do they switch on immediately?

LED bulbs do not require any time to warm up, when they are switched on they are instantly on.

Does the level of light produced by LEDs reduce over the lifetime of the bulb?

The level of illumination does reduce over the life cycle of an LED bulb, however due to their incredibly long life span this would be barely noticeable, if at all.

How can I save money on my electricity bill?

The best way to save money on your energy bill is to replace halogen and incandescent lights with LED lights throughout your home and business. This quick and easy switch can help you cut your lighting bill by up to an enormous 90%.

Do I need a LED-compatible transformer?

It is recommended that you have a LED compatible transformer (also known as a driver) if you are buying 12v bulbs such as LED strip lights, MR16, MR11 and G4 LED bulbs. The main purpose of the driver is to ensure there is a constant current going to the LED in the required voltage.

You may find that your LED bulbs work fine with a standard transformer, however this could reduce the life span of your bulb and you may also find your LED bulb flickers because it is receiving an unsuitable current and can cause permanent damage. Therefore, to avoid potentially breaking your LED bulbs, using LED drivers/transformers for your 12v bulbs is highly recommended.

Is switching from halogen to LED lights cost-effective?

LED lights are much more energy efficient than halogen bulbs and making the switch to LED bulbs will result in significant savings on your electricity bill throughout the life span of your bulbs. You can save up to 90% on your lighting bill just by making the switch.

Are LED light bulbs compatible with dimmers?

Many of our LED bulbs are dimmer compatible, you will see ‘dimmable’ on the dropdown menu when selecting your lights if this option is available. We recommend using a trailing edge or low voltage LED dimmer switch to operate dimmable LEDs.

What are the benefits of LED lighting?

LED lights have a huge number of benefits, these are our favourites:

  • Extremely energy efficient
  • Eco-friendly lighting
  • Low temperature operation
  • Significant savings on your electricity bills
  • Low profile and compact size
  • No IR or UV emissions
  • Much longer life-span than halogen bulbs
  • Breakage and vibration resistance
  • Directional light
  • Life unaffected by rapid cycling
  • Instant switch on with no warm up time

Why won’t my dimmer switch work with my LED lights?

There could be a couple of reasons for this:

  1. Are your LED bulbs dimmable? Not all have the ability to dim so you must ensure that you have chosen the dimmable option.
  2. Do you have a trailing edge or LED compatible dimmer switch? Standard household dimmers are leading edge which are not compatible with LED bulbs. If this is the problem, you can find a selection of trailing edge LED dimmer switches on LEDTrader.

Can I use LEDs on a 12-volt circuit?

Yes, providing you use MR16 LED's and that you change the transformer to a LED transformer, if you want to dim them you will need to change the transformer to a dimmable version

Is a low voltage circuit or a mains circuit better for LED lights?

You can use either but a mains circuit historically has fewer problems

What is a GU5 LED bulb?

GU5 is another name for MR16 bulbs, therefore if you are looking for GU5 LED bulbs, you will find these under our MR16 LED bulb section.

What are SMDs?

SMDs are Surface Mounted Diodes and they are the new generation of LED lighting. The majority of LEDTrader’s bulbs contain SMDs and these are up to three times brighter than older LED bulbs on the market.

What SMD chips are used in our LED bulbs?

LEDTrader only use the highest quality of SMD chips in our extensive range of LED bulbs giving excellent levels of reliability, a very high quality of light and energy efficiency.

What does 3528 mean?

3528 refers to the size of the SMD chip in mm, 3528 equates to a 3.5mm x 2.8mm chip size.

What does 5050 mean?

5050 refers to the size of the SMD chip in mm, 5050 equates to a 5mm x 5mm chip size.

Do I need to replace existing light fittings to use LED bulbs?

No you shouldn’t need to replace your light fittings.  The majority of our LED bulbs are designed to be retrofit, meaning that our LED light bulbs are made to fit perfectly in to existing light fittings. However, we advise that you check the product information to ensure that you are looking at the correct bulbs to match your fittings.

Will I need specific fittings for bathroom lighting?

In order to comply with building regulations, any LED lighting fittings which are going to be used within a bathroom, shower room or wet room should be IP65 rated or higher. This will ensure that they are waterproof.

What does IP65 and IP67 mean?

The IP (Ingress Protection) rating of electrical products is a guide used to communicate the strength of the enclosure surrounding electrical components.

In the case of LED lights bulbs, this rating measures the protection against both dust particles and water.

IP65 rated LED bulbs are fully protected against dust particles and water jets from any direction.

IP67 rated LED bulbs are fully protected against both dust particles and the immersion of water from 6-39 inches in depth.

Do I need to have fire-rated fittings?

When recessed downlights are installed, ceilings are punctured which can reduce the effectiveness of the ceiling as a barrier for preventing the spread of both fire and noise. There is no need to panic about this if you require LED downlights in your home or business as fire rated light fittings are fully compliant with building regulations and help to protect the building from both the spread of fire and noise pollution.

Which colours are best for both indoor and outdoor use?

Colour choice is 100% down to personal preference. However, the most popular colour purchased for indoor LED lights is warm white as this is the closest colour to that given off by standard halogen spotlights. The most popular choice for outdoor lighting is the cool white which gives a bright crisp light which is often preferred for outdoors.
