Lightbulbs FAQs

How to dispose of light bulbs?

This entirely depends on the individual light bulb types you have in your home, but luckily, we’ve got a quick guide for how to throw away or recycle your used light bulbs.

Can you recycle light bulbs?

  • Incandescent light bulbs or your ‘standard light bulbs’ can be thrown away in your normal household waste bin, but other types of light bulbs need specialist care. This is the same for Halogen light bulbs, as both types of bulbs have very fine wires that are time-consuming to remove during the recycling process.
  • Compact fluorescent lamps (CFL), more commonly known as eco or energy saving bulbs, can be recycled at a local recycling point. There’s nothing currently stopping you from throwing them away in your household bin, but they contain valuable parts such as glass and metal that are easy to separate out, so it’s more eco-friendly to recycle them if you can find the time to drop them off.
  • LED light bulbs, if retrofitted, can be recycled but may come with a recycling fee. You’re free to either recycle them at a local recycling point or throw away individual bulbs in your household bin since there’s currently nothing in place to prohibit this.
  • Fluorescent tube light bulbs can’t be thrown away in your normal bin; they need to be recycled at your local recycling point. This is because they contain components like mercury that are harmless to us when used in the light fixtures and lamps, but that do need to be recycled responsibly. This also means the valuable materials like glass and metal can be collected and used again and again.
  • What light bulb do I need?

    Because the world of light bulb types is both vast and specific to your lamp or lighting fixture, it’s not always clear which light bulb you need. Well, let us illuminate this for you! For more tips, check out our Light Bulb Buying Guide

    The cap fitting

    You need to know which cap fitting to use for your lamp or light. You can do this by checking the lamp’s adhesive label (if you’ve kept it attached to the wire) that will tell you which cap it needs (common names you might recognise are the bayonet cap and the Edison screw cap). If you’ve removed the label, check the current or expired bulb’s base and it will tell you which fitting and size it is. If you already know the fitting and wattage details you’re looking for, this will be displayed on the new bulb’s packaging.

    The wattage

    The wattage, or watts, of a bulb is the measure of how much power the light bulb consumes, not the brightness. Each lighting fixture, whether a lamp or a ceiling light, has a wattage bracket, and you can usually find this by looking at the bulb’s packaging, light specifications, or on the expired bulb itself.

    The lumens

    The lumens is the brightness of the bulb, so a bulb with low wattage but high lumens means higher energy efficiency to light output. Choosing the lumens you want for your light bulb depends on where you’re going to be using it. For desk and tabletop lamps, for example, you’ll probably want lower lumens than for your hanging ceiling light. Lower lumens mean softer, more ambient light, and higher lumens means brighter, so you can achieve the correct lighting level for the fixture you’re replacing.

    The Kelvins, or warm and cool light

    The Kelvins of your light bulb means the warmth of the light. Lower Kelvins means warmer, softer lighting perfect for bedrooms and living rooms. Bulbs with higher Kelvins are crisper, brighter, and often whiter, so they’re popular for use in kitchens, bathrooms, studies, and working areas.

    How long do light bulbs last?

    Your average light bulb, the standard incandescent bulb we mentioned earlier, can last anywhere between 750 hours (over 31 continuous days) to 2,000 hours (around 83 continuous days). Because you will, presumably, not have the light on at all hours of the day every day, your light bulb could therefore last you months before it needs replacing.

    This differs from other light bulb types. For example, fluorescent tube lighting is a longer-lasting light bulb, which is why they’re favoured by businesses and large rooms in the home. They can last anywhere from 24,000 hours (1,000 days) to 36,000 hours (1,500 days), depending on the size and power output of the lighting you choose.
