GU10 LED Quick Facts
- GU10 stands for ‘general use’.
- The ‘10’ refers to the 10 mm space between the two prongs, or legs of the bulb. GU10 LED light bulbs have anarrow base with a slightly wider aperture.
- Sizes are 50mm diameter and up to 75mm in length.
- They can usually retrofit into any existing halogen fitting.
- Energy use is far lower than halogen equivalents with bulbs generally using 10x less energy.
- Most commonly, GU10 LED’s are used for ambient lighting requirements but due to a wide range of colourtemperatures and beam angles, can easily be used for task lighting in kitchens and bathrooms.
- Spotlight GU10’s can sometimes be confused with integrated downlights where the entire bulb and fitting issupplied. Spotlights are cheaper and work with any type of compatible fixture.
- Bulbs range in temperature from 2700k extra warm white through to 6500K daylight.
- Lifespan for domestic applications is around 15,000 hours. For retail and industrial use, this ranges from25,000 to 50,000 hours.
- Colour rendering is >80 in most cases but some manufacturers ranges now offer almost sunlight qualityrendering of colour.
- You will need a specific water resistant bulb for some bathroom applications.
- GU10 LED’s do not have a fire rating. However, there is usually a fitting around the GU10, making itfire rated.
Mini Guides: Helping You Buy Correctly
We have produced a series of mini guides to help you choose the right GU10. Each guide is a 4-5 minute read andshould give you enough information to get your purchase correct.
Selecting by Specification: Colour Temperatures & Rendering
You can choose from different colour outputs measured in Kelvins.
- Extra Warm White (2700k)
- Warm white (3000K – 3500K)
- Cool white (3500K – 4500K)
- Daylight (4500K – 7000K)
Identifying the right colour temperature largely depends on whether you are using the LED’s for Task, Ambient orAccent lighting.
If colour rendering is crucial to you – and it will be if you are buying spotlights to showcase colour in itemssuch as clothing, shoes, jewellery & cars - you will need to pay attention to the colour rendering rating of thespotlights you are buying.
We discuss all this and much more in our quick read guide. Read our quick read guide here – Choosing the best LED GU10’s by colour
Seleting by specification: Wattages & Lumens
In general, the higher the wattage of bulb, the more lumen output will be produced.
Lumens | LED Wattage |
220 - 400 lm | 2 – 6W |
400- 600 lm | 6 – 8 W |
600 - 1100 lm | 10 – 12 W |
It pays to shop around because some bulbs can produce outstanding lumen outputs without pushing up energyconsumption. Osram for example have some great 6Wbulbs that produce a whopping 575 lumens.
