LED Spotlights

Find out about Energy Efficient LED spotlights


It is recommended that all old style incandescent light bulbs are replaced with Compact Fluorescent Light (1) (CFL) bulbs or LED bulbs to reduce electricity consumption.

Mains powered CFL and LED Spotlights

A typical CFL has a lifetime many times that of an incandescent bulb, and consumes only 20% of the energy. This made them the obvious choice until around 2010/2011 when LED bulb technology took a massive leap forward. Previously, although LED bulbs offered enormous electricity consumption reductions, they suffered from a couple of problems:
The light from an LED is very directional and so LED bulbs were only really suitable for spotlighting directly over work surfaces etc. These bulbs (of the type shown below) also tended to be quite dim compared to their halogen equivalents and so they were rather disappointing for general room lighting. BUT technology moves quickly, and at the time of updating this article (January 2013) these problems are history (as long as you choose the right bulbs to replace your existing incandescent/halogen bulbs).

Replacing Halogen Spotlight Bulbs with LEDs

Typical 50W halogen bulb from a Spotlight

During the last 10-15 years, halogen spotlights have become more and more popular in British homes. Halogen bulbs (pictured above) are typically available in low voltage 6V or more commonly 12V (MR16 fitting, supplied with a transformer) and mains voltage 240V (GU10) versions with 20-50 Watt power ratings.

LED spotlight prices have tumbled recently so that they are not that much more expensive than the dichroic halogen bulbs that they replace. Halogens typically sell for £1 or more each - equivalent LED spotlights are now available from as little as £2 each, BUT whereas a halogen will last for around 1,000 hours on average and consume 35 or 50 Watts typically, an LED spotlight producing the equivalent amount of light will last for up to 50,000 hours with a total power consumption of only 3 Watts - 50 times the lifetime and one tenth the power consumption!

LED Spotlight Options

240V LED Spotlight

LED Spotlights are now available with optical beam angles from 6 degrees (very directional spotlighting for reading lights or workbenches to 60+ degrees (for general lighting). They also come in industry standard fittings: MR16, and GU10 so you can very simply replace all the spotlight bulbs in your home and start saving on your electricity bill (2) each month.

Buy LED Spotlights


Buy MR16 and GU10 LED spotlight bulbs from eBay

The cheapest places to purchase LED spotlights is still eBay (3). A huge range of different colours and light intensities are available from as little as £2.00 including postage. Click here to search eBay now for MR16 LED (4) (12 VDC or 12 VAC), and here for GU10 LED (5) (mains powered 110/240 VAC).

12V LED Spotlights and Renewable Energy

12 Volt LED Spotlights are being used more and more in off-grid renewable energy situations where an array of solar panels (10), or a wind turbine (11), is charging a 12 volt battery bank (12) with power. Using 12 volt appliances, devices, and lighting costs a little more up front, but there are no energy losses caused by having to step up voltage to 240V AC using an inefficient power inverter (13) if you use 12 volts throughout. A typical power inverter burns up around 50 Watts of power just converting DC from the batteries to AC - enough power to light fifty 12 volt LED spotlights.
nb. This only works well if the battery bank (14) is close to the site where you intend to use the stored power or there are voltage losses (15) over the cables.

12V LED spotlight bulbs and MR16 bulb holders

12V LED spotlights (17) (pictured above) and MR16 ceramic bulb holders (18) are available from the REUK Shop (19).
