FAQs


Find answers to the most commonly asked questions about ordering from The Lightbulb Company here. If you have a query that isn't answered here, please get in touch.

What caps / bases do I need?

With so many different caps and bases available, it is sometimes somewhat tricky to find exactly what you need. We have compiled a list of all the most popular caps and bases to help you identify the right bulbs for you which you can view here. If you are still in doubt, please do not hesitate to call our friendly Customer Service team (01869 362222) or email us at: sales@thelightbulb.co.uk and we will happily assist you.

What is colour temperature?

All light bulbs have a specific burning colour temperature measured in Kelvin degrees. This best describes the feel of a bulb, our bulbs come in two main colour temperatures; warm white and cool white.

What does voltage mean?

This is a measurement of the volts required to operate the bulb, the standard for the UK is 240 volts.

What is a beam angle?

Measured in degrees, the beam angle describes how wide the light is spread. Bulbs with a narrow beam angle create a spotting effect and are suitable for highlighting particular features of a room. Bulbs with a wide beam angle create a flooding effect and are better for general ambience.

The most common beam angles for the domestic home are 24-26 degree (medium) or 36-38 degree (wide). Beam angles can be as low as 6-8 degrees to produce a precise spot of light to the 100 degree plus beams for very general floodlighting.

Why are lumens important?

The lumen count of a bulb will let you know how bright the bulb will be, with LED bulbs being designed to use very little energy, estimating brightness in wattage is no longer accurate. As a rule, the higher the lumens, the brighter your bulb will be.

What colour option should I choose?

This is completely down to personal preference. Most of our bulbs come in several colours, of which the most commonly used are Warm White and Cool White. Warm White has a softer feel and is ideal for living areas and bedrooms while Cool White is brighter and whiter and is therefore used mainly used in kitchens and bathrooms.

Why should I buy branded bulbs?

The importance of buying a branded light bulb cannot be overstated, there are four leading manufacturers of light bulbs in the world today: GE lighting, PHILIPS, OSRAM and Sylvania. Whilst there are of course a number of very reputable and respected smaller manufacturers of light bulbs throughout the world. These main four account for a considerable percentage of the consumption across the globe.

The reason for this of course is the same as with any other product. The key factors in purchasing any item for any consumer is the knowledge and comfort that in the event of any difficulty or problem with the item, the manufacturer and associated supplier will endeavour to resolve the issue to your complete satisfaction. Dealing with major international organisations of this stature provides that security.

We at The Lightbulb Company are proud stockists of all four major brands. We hold direct accounts with each of them and purchase direct from each of them. A fact most of our competitors cannot claim to (ask them?). The advantages of such an established direct relationship are of course essential. The manufacturer warranties and guarantees are only applicable if purchased through recognised stockists and respected partners. Many online light bulb suppliers supply inferior unbranded products that afford very little recourse in the event of difficulty. Again, we at The Lightbulb Company have a fully stocked UK  based warehouse operation available for inspection by anyone at any time.

What is an LED?

LEDs (light-emitting diodes) are a type of electronic light source. LEDs are different from conventional light sources such as incandescent and halogen lamps. They last much longer, consume far less energy and emit very little heat. They are highly durable and do not feature fragile elements such as glass tubes or filaments; they are also safer because they do not contain any mercury or lead. LED Bulbs are now available in the most common light fittings, including GU10, B22, E27 and MR16.

How much power do LEDs use?

LED Bulbs use up to 90% less energy than an incandescent or halogen bulb of equivalent brightness. LEDs are far more efficient at converting electricity, measured in watts, into light, measured in lumens. As such, a typical 4 watt LED bulb can easily achieve a light output comparable to a 50 watt halogen, sometimes higher due to its high lumen to watt ratio.

How long do LEDs last?

Due to very efficient thermal management, LED Bulbs are able to remove heat through heat sinks to help prolong the life expectancy of the bulb by slowing down lumen depreciation. A well-built LED with good thermal management should last at least 20,000 hours. Be wary of retailers making exaggerated claims about the life expectancy of their products.

Another important aspect to take into consideration is that all light bulb ratings are carried out under perfect laboratory conditions. There are numerous other factors that will determine the life of any light bulb. Electrical surges, extreme cold, vibration and extreme heat are just a few examples of instances where the Life time of the product will be affected. Any number of factors could determine the performance and ultimately the life of a light bulb.

How bright are LEDs?

The brightness of a bulb is measured in lumens (Lm), the higher the number of lumens, the brighter the bulb. Despite using very low wattages, LEDs are able to emit the same brightness as traditional light sources. To make things easier, most retailers quote an equivalent incandescent wattage so consumers can replace their lights and keep the same brightness.

How can LEDs help me save money?

Whether it's in a standard household or a commercial environment, lighting represents as much as 20% of the overall energy consumption. By switching LED, a considerable amount of money can be saved due to the lower wattages of the products. LEDs also last far longer so you won't need to replace them often and their reliability means you won't need to worry about maintenance.

Are LEDs safe?

Yes. Unlike CFLs (Compact Fluorescent Lamps), LEDs do not contain mercury. They also give off comparatively little heat, making them safer to handle after prolonged use. The absence of glass enclosures and fragile parts also reduces the likelihood of breakage, so you won't have to worry about broken glass.

Will your LED Bulbs work in my existing fittings?

Yes, all our LED bulbs are designed to work with existing light fittings and be used as direct replacements. Please ensure that any fittings being placed in bathrooms are both fire rated and waterproof and hold suitable certification of IP65 or higher to comply with relevant building regulations for bathrooms.

Are your LED Bulbs dimmable?

We offer both dimmable and non-dimmable LED Bulb options; you will find these on our respective product pages.

Do I need to use a special dimmer for LED dimmable bulbs?

Yes. LEDs  use very little power compared to halogen bulbs. While this is good news for your electricity bills, it also means they will not work with your existing dimmer switches. You can find suitable dimmer switches on our respective dimmable bulb product pages.

Do LEDs come on immediately or do they need to warm up?

Unlike CFLs, which usually take a few minutes to reach full brightness, LEDs reach full brightness instantaneously.

What is an SMD LED?

SMDs are the new generation of LED lighting, the majority of our bulbs contain SMD chips allowing our bulbs to be much brighter than older generations of LED.

What is a COB LED?

Chip on Board (COB) is the most recent development in LED technology using chips with multiple diodes (typically 9, or more). COB offers a greatly improved Lumen per Watt ratio compared with other LED technologies such as DIP and SMD.

What are LED Strip Lights?

LED Strip Lights, sometimes called LED Tape or LED Ribbon, are long, flexible strips of LEDs with a self-adhesive backing that are commonly used for cabinet lighting in the kitchen or to create subtle lighting effects. Being flexible, LED Strip Lights can be used on surfaces that aren't necessarily flat. They can also be cut to length.

What is the difference between 3528 and 5050?

This refers to the size of the SMD chips inside the LEDs, 3258 means the chip is 3.5mm x 2.8mm and a 5050 is 5mm x 5mm.

What does RGB mean?

RGB stands for red, green and blue and refers to the three coloured diodes that go into making a single RGB LED. By mixing different amounts of red, green and blue light, these LEDs can be programmed to display various different coloured lights, including white.

What is the difference between IP44 & IP65?

The IP, or Ingress Protection rating of an electrical product is a guide that is used to detail the strength of the enclosure that surrounds the electrical components.

In the case of LED strip lights, the IP-rating measures the tolerance to the effect of dust particles and the level of protection against water or liquids.

IP 44 is perfectly suited for indoor use, but for more protection against dust and low-pressure jets and sprays, we highly recommend an IP65 rating.

How should I dispose of my bulbs and batteries?

The Waste Electrical and Electronic Equipment (WEEE) Directive is now UK law. The legislation aims to make producers pay for the collection, treatment and recovery of waste electrical equipment. The regulations also mean that suppliers of equipment like high street shops and internet retailers must allow consumers to return their waste equipment free of charge.

The amount of WEEE we throw away is increasing by around 5% each year, making it the fastest growing waste stream in the UK. Recycling reduces the environmental and health risks associated with sending electrical goods to landfill.

We are obliged under these regulations to offer our customers free take-back of their WEEE on a like-for-like basis when they buy a new Electrical or Electronic product from us. Customers must return their like-for-like WEEE item to us within 28 days of purchasing their new item. Under the WEEE Regulations, all new electrical goods should be marked with the crossed-out wheeled bin symbol and be disposed of separately from normal household waste.

Relevant legislation:

  • Environmental Protection Act 1990 [EPA]
  • Health & Safety at Work etc. Act 1974 [HASAWA]
  • Integrated Pollution and Prevention Control Act 1999 [IPPC]
  • Control of Substances Hazardous to Heath [COSHH]
  • Waste Electrical & Electronic Equipment Directive [WEEE]

There are further obligations under Duty of Care legislation.

All types of fluorescent and discharge lamps are now classified as 'Hazardous Waste' in line with the new WEEE Directive.

In order to comply with this legislation, businesses must manage the disposal / recycling of their hazardous lamps in a responsible manner to satisfy the statutory responsibility for the health and safety of employees at work and the impact upon the environment of the business. This includes a duty of care for users of lamps and tubes to take all reasonable steps to look after this waste and prevent its illegal disposal.

Most fluorescent lamps contain potentially harmful substances - especially mercury, lead and cadmium, which can be absorbed through inhalation or skin contact. Other lamps contain sodium which reacts with water (which may be present in the air) to produce potentially explosive or flammable gases.

As well as the injury hazard of glass from broken tubes, the contents - in the form of dust and chemicals - must also be treated as a potential hazard.

Please contact us at lampdisposals@thelightbulb.co.uk for more details of our lamp disposal service.
