LED bulb FAQ
LED bulbs are a new technology, but they are evolving fast. With the 2009 ban on traditional light bulbs over a certain wattage, LED bulbs are a feasible and cost-effective solution for any environment.
Some of the regular questions we get asked are:
Aren't LED bulbs expensive?
No. The cost has come down considerably in the last few years and can cost from as little as £1. Although more expensive than the traditional incadescent bulbs, they use up to 80% less energy, lowering your bills, but also last many times longer - some as much as 20 times longer and up to 50,000 hours.
Can LED bulbs replace recessed halogen bulbs?
Yes they can. The fittings (GU10, MR11, MR16 etc) are the same and they can be plugged in. Some work with lower voltages so need a transformer, and others will just slot straight in.
Can LED bulbs work on dimmer switches?
Yes they can. Although you should check the specifications of each type of bulb to ensure it works where you want it to go.
Don't LED bulbs offer an inferior light quality?
Sometimes yes but it depends on the power of the bulb. The Lumen output of bulbs (the power of the light generated) gives an indication of brightness. With LED light bulbs, the number of LEDs on the "bulb" itself determines the brightness. The number of LEDs is typically 16, 24 or 48 with the 48 LEDs giving the equivalent of a 40+ Watt halogen bulb.
How long do LED bulbs last?
Typically they last 24,000+ hours.
Do LED bulbs suffer from taking time to warm-up?
Conventional energy saving bulbs can take a few minutes to warm up to full brightness, but LED bulbs can warm up within 1/2 second - giving instantaneous light.
