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.


Made to replace a 20W halogen G4

LED miniatures are available in 2 different colour temperatures: Warm White (often used in living areas for a warmer atmosphere) and Daylight (a mix between the two and provides a crisp white colour).

LED bulbs are highly energy efficient, using up to 90% less energy than traditional lighting sources. The average household lighting bill is £300 a year and switching over to LED could save you £270, which turns into thousands over the bulbs predicted 15 year lifespan.

What about my existing transformer?

G4 bulbs will only work on a 240v Mains circuit when being powered by a compatible 12v Transformer. Alternatively, the G4 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 and to maximise your perpetual savings. Please contact us for advice or assistance if unsure how to proceed.

On selected LUMiLiFE products, we offer an automatic 3 year warranty. This entitles you to unlimited replacements from the original purchase throughout the warranty period. If your original purchase is no longer available, a new replacement with the latest equivalent model will be offered.

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.

I used these bulbs to replace my under cupboard lights. They are cooler and safe to touch and gives me the type of light I wanted. I didn’t even have to change the transformers on the cupboard tops.

I recommend LEDHUT to anyone intending to replace their incandescent bulbs.
13th June 2018
Bigger than lamps that they replaced and didn’t fit well
05th May 2018
Used for bedside reading lamps, just that bit of extra wattage over the 1.2W G4s from LEDHut makes all the difference. Quality excellent judging by the lower wattage G4s and the ***$s seem just as good so far
04th May 2018

23rd January 2018
I never saw what size they were so unfortunately they don’t fit that well in my cooker hood. My fault my problem
19th January 2018
product is for a cooker hood and I needed to switch from halogen to LED as the halogens were generating too much heat. The LEDs have fixed this problem. I would recommend anyone with halogens to switch to LEDs.
10th July 2017
Capsule used in a promotional display to highlight a small area. Fits the old halogen fitting well and is brighter than the 20W unit before!
03rd July 2017
Excellent all round.
23rd June 2017
Kitchen down lights. Used them in a client's house. Very good, just a bit too bulky to fit easily into the holder.
07th June 2017
Product OK.
12th May 2017
Arrived following day and provide a crisp, clean light - much better than my old halogen bulbs
07th May 2017
Slighty bigger than I thought so next time I'd taking a slighly smaller type. Other than that seems good quality-no heat either.
01st May 2017
The product is used to illuminate a china display cabinet. It is used for 9-10h daily every day. Unfortunately the drivers have failed within a year for the first and second (free) replacement. I am now using the third (free) replacement bulb.
30th March 2017
A robust and apparently well sealed unit, these were bought to replace 20W G4 Halogen "sideways on" capsules in small standard lamps with relatively large reflectors. Chose to leave the frosted glass off as the capsule is quite large in diameter. The light is of comparable in colour & slightly brighter than the Halogens. No noticeable noise in operation.
21st March 2017
Oven hood lights - only negative which is not a prob is the bulbs were slightly bigger than those in the hood already so bit of a squeeze getting them in
06th March 2017
very good
25th February 2017
As a leak light for woodwind instruments
16th November 2016
Display cabinet lighting.

30th October 2016
great little replacement for a table lamp halogen which used to get so hot. only lost 1 star because it is not available in cool white (6000-7000k) version.
26th October 2016
Replacement for halogen.
07th October 2016
Lamp too bit to fit housing
29th September 2016
As bright as the old G4 it replaces. Have modified the lamp holders because the LED bulbs are a little larger and would not fit.
28th July 2016
Replacement for desk lamp bulb
08th July 2016
Replacement for desk lamp bulb
08th July 2016
Direct swap, wouldn't know its a LED Light
26th June 2016
Cheap and extremely bright!! Really only need 3 but the shade needs five. Small company and discreet
30th May 2016
Can't fault the product. Well designed. Great output.
27th May 2016
The bulbs have been used to replace a set of counter downlights in my kitchen. Although described as "Warm white" the light is fairly blue-grey in colour, when compared with the conventional quartz halogen alternatives. The combination of these bulbs and the LED transformer partly interferes with our radio which is sited on the opposite side of the kitchen wall (concrete block construction) to produce a background hissing noise when the lights are switched on.
