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.



B15 base

Also commonly known as the ‘SBC’ or ‘Small Bayonet’. The most popular B15 or SBC is 15mm and with two locating lugs.

Consume up to 90% less power

LUMiLife B15 bulbs provide an outstanding life time expectation of up to 25,000 hours (approx. 3 years of continuous operation). With traditional halogen/incandescent lighting, 80% of the electricity is lost through heat. LED lighting run significantly cooler as heat is dissipated by metal sinks that take heat away from the light source – this maintains the lifespan of the LED bulb.

Easy to replace

All our bulbs have been designed to directly replace your old halogens, it truly is as easy as changing a lightbulb! As well as having identical fittings, LEDs can also offer you the same level of brightness as your current bulbs. LED bulbs are available in 2 different colour temperatures: Warm White (often used in living areas and gives off a softer glow) and Cool White (often used in kitchens and bathrooms).

What about my existing dimmer switch?

Typically the majority of leading edge dimmer switches have a minimum wattage of 60W, which is far too high for dimmable LED bulbs. This is why you need an LED compatible dimmer switch when you purchase your bulbs. Please note that our lamps will not work with touch or remote control dimmers – this includes touch lamps

5 year warranty

All LUMiLife LED products come with a standard 2-year warranty. With our LUMiLife products you can extend your warranty cover to five years by completing and returning our extended warranty form

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 Power

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.


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.

Fitting 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 (Option)

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.

Use 5 in one fitting. The product bought a year ago was a 4.5watt bulb. As a replacement for 'traditional' bulbs they are good. However, in just over a year I have had one bulb fail completely and one bulb with excessive flickering. These have been replaced by 5 watt bulbs under the 2 year warranty. The 'colour' is different - they are both described as warm white, but they are not the same. So overall OK, but not great.

A very good product used as a replacement for our old compact fluorescent bulbs; just as bright and half the wattage.

Used in a three-prong free-standing lamp, replacing 40w 'ordinary' bulbs. Light quality and brightness is a very good match, although the fact the LED bulbs are slightly longer in size may be an issue for some. Very pleased and I will be interested to see how long they last - possibly longer than me?

Replacements for old style bulbs. Running at one eigth of old 40w. Old bulbs used to blow fairly regularly due to small size of golf ball and hot elements, making short lifespans. LED runs cooler, hopefully lasting longer! No quality issues so far. Used in dining room, seems to go well
