How did we calculate these results?

We’ve taken the current average UK electricity rate of 15p kWh, and the closest standard LED replacement bulb to determine the financial benefits of changing to LED. Calculations based on a 6 hours per day usage. Savings vary depending on electricity supplier.


LED Spotlights are designed to replace your existing halogen range. LED lighting is highly efficient as it uses 90% less energy than the traditional lighting sources - saving you more money. We aim to make choosing which product is right for you as easy as possible; whether you're looking for a particular size, colour, wattage or lumen output.

This particular spotlight is non-dimmable, however, we do have dimmable MR16 spotlights available in our spotlight categories. If you are choosing a dimmable LED, you may require a Trailing Edge dimmer switch. Please contact us if you’re unsure on your dimmer switch compatibility.

MR16 units will only work on a 240v mains circuit when being powered by a compatible 12v transformer. Alternatively, the MR16 units can work on a dedicated 12V DC circuit without the requirement of a transformer. While these units are compatible with the majority of electronic transformers, we cannot guarantee compatibility for all. For optimum efficiency, we advise that you change your existing transformers to LED Drivers to guarantee compatibility. Please contact us for advice or assistance if unsure how to proceed.

Since LED light bulbs are designed to use less energy than halogen spots, wattage is not a reliable way to gauge how bright the bulb is. Brightness is measured in Lumens.

With LED spotlights there is more to consider than just a direct Lumen comparison with the halogen equivalent. The superior light quality given off by LEDs and much lower bulb degradation rate over time must also be taken into account. This is why the stated Lumen output for an LED spotlight is often less than that quoted for a halogen spot bulb it replaces.

Beam Angle°

The beam angle is how wide the beam is spread. If you have a very narrow beam angle your light will be projected like a handheld torch whereas if you have a wide beam angle it will be much softer and spread like a traditional bulb. Wide beam angle are best for living areas such as living rooms, dining rooms and bedrooms where you are looking for a softer light and narrow beam angles for targeting specific areas or for decoration.

Power Consumption (W)

The wattage is the value given to the energy consumed by the light bulb itself. So, a 50-watt halogen spotlight bulb will use 50 watts of power. If you have 6 x 50-watt halogen spots in your kitchen then you will be using 300 watts of power. If you were using replacement LED lights at 4 watts each you would be using 24 watts of power, resulting in huge energy savings.

Input Voltage

This is a measurement of the volts required to operate the bulb. The standard for the UK is 240 volts. This means that you can plug these directly into existing fittings without changing any of the electrics.

Height (mm)

The size determines the diameter and the length of the bulb. In most cases the bulbs are a retro-fit, which means they are a direct replacement for their halogen equivalent.

Width (mm)

The size determines the diameter and the length of the bulb. In most cases the bulbs are a retro-fit, which means they are a direct replacement for their halogen equivalent.

Depth (mm)

The size determines the diameter and the length of the bulb. In most cases the bulbs are a retro-fit, which means they are a direct replacement for their halogen equivalent.

Wattage Replacement

This details what this LED bulb is a replacement for in terms of standard halogen bulb wattage. This allows you to easily make a comparison when replacing your existing halogen bulb, to ensure you get a similar light quality and brightness from your new LED bulb

Average Life in Hrs

Manufacturers will give lifetime claims in multiples of 1000 hours. One thousand hours is equivalent to about 6-months use when the bulb is on for 4 hours per day. A traditional halogen spotlight bulb is expected to last about one year (2000 hours) where as an LED will last between 30,000 and 50,000 hours - that’s between 15 and 25 years! Switching to LEDs means you may never have to change your light bulbs again.

Base Type

This is the fitting of the bulb, described by a letter/number code. You can find out what your fitting is by looking on the base of the bulb you are replacing or the packaging of your existing bulb.


Dimmable LED bulbs are only compatible with a dedicated "Trailing Edge" dimmer switch that reduces the current flow. Your bulbs will not work effectively if used with the conventional "Leading Edge" dimmer switches that operate with a higher current flow.

When ordering dimmable LEDs please ensure you have an LED-compatible Dimmer Switch.

Protection Rating

The IP rating is an international classification system for the sealing effectiveness of enclosures of electrical equipment against the intrusion into the equipment of foreign bodies (i.e. tools, dust, fingers) and moisture. IP65 for example, is dust tight and water resistant.

Colour Rendering Index (CRI)

Measured on a scale from 0 to 100 percent, the colour rendering index (CRI) indicates a bulb's ability to make reds, greens, and all other shades look just the way they should. Simply put, the higher the CRI, the more accurate an object's colour would look under the light source.

These item were used to replace low voltage (12v) light fittings in an overhead shower extractor fan. It now provides a brighter beam that matches the other overhead LED (240v) spotlights.

will use again
10th November 2016
I have recommended the LEDs to all me friends,so i have become known as the local LED rep ! Other bulbs got hot which could lead to fire. LEDs do not heat up provided you use correct wattage. Much safer and a 7 year life span for the bulbs and spotlights.

These are used in the home to replace existing 35w bulbs and are just as bright.

Five stars
12th December 2015
We bought these LED bulbs for a bathroom to replace 50w halogen bulbs. We chose the daylight colour and they provide plenty of brightness and are not as blue looking as the cool white. The colour for a bathroom is fine but for a lounge or bedroom I would probably go for the warm white.
03rd December 2015
Gives a great light
19th November 2015
Good quality bulbs - much better than ones I have bought in the past
12th November 2015
worked well once I replaced the old transformers with LED driver
