Introducing ProLED

Our ProLED range of spotlights brings greater energy-efficiency than ever before. You’ll be getting many more lumens per wattage with a ProLED. They utilise a much-improved array of reflective panels internally to focus the light into much narrower areas, making them much better. They have massively upgraded heat sinks, meaning greater heat dissipation, and longer lifespans.

Newest Advancements In LED Technology At Highly Competitive Rates

This product features one large COB LED. Alongside its multifaceted reflector, the 6w COB can emit a beam angle of 60°. The evolution from SMD to COB spotlights has made LEDs a closer replacement than ever before.

The 400 Lumen brightness makes the 6w COB a close replacement to 50w halogen spotlights, whilst having two colours to suit more situations than any 50w halogen spotlight before.

One of the available colours, Warm White, has a light colour of 3000K which makes it the perfect replacement for any spotlights in your bedroom or living rooms as well as rooms that have a more traditional decor as the Warm Colour suits the style of the room very well.

The other available colour is Cool White and is 6000K. The bright, White light emitted from Cool White is mainly used in rooms that need more light such as bathrooms and kitchens. Cool White is also used in rooms that have a modern decor to them.

Give Another Dimension To Your Room With Dimmable LED Spotlights

Like all of our MR16 LED spotlights, the 6w COBs are available to be dimmed with the right equipment. If you have a compatible LED dimmer switch and dimmable LED driver, then you can dim low voltage LED spotlights exactly like traditional ones.

Important notice about dimmable LED lights

Each 6w COB has a life expectancy of up to 50,000 hours meaning you can expect up to 15 years worth of life and even more if you were to dim them.

Great bulb looks well made.


Good service lamp does the job.


Great light a beam spread. Much better than cheaper alternatives for a bathroom.

I bought these lamps as replacements for 50W tungsten flood lamps. The diameter is the same but the body is slightly longer, so they fit the existing light fittings but project slightly. They give a very even light but the colour is cooler than tungsten light even though they are designated 'warm white'. I am satisfied with the lamps but they are not a perfect substitute for 50W tungsten.

Colin Winchester

The extra wattage over the usual 4w bulbs has make a tremendous difference to a bathroom with no windows. It's much brighter now.

Murad Haibatan

Excellent product just what I needed after an extensive search against other big manufacturer

Daryush Moussavi

Very bright. Really like the wide spread of light. Solid metal build. Love the big single LED in the middle. Perfect light temperature for bathrooms. Ridiculously efficient. Cost savings and reduced CO2 emissions top off a great product.

Steven Hardaker

These lamps are a very good replacement for halogens. They look very similar a fraction brighter than the 50w halogens they replaced. I have tried other led bulbs which are either too dark or give a horible greeny tint to the lighting. I would highly recomed these lamps

James Hobbs

Great price and great quality. Couldn't ask for more! Thank you for the recommendation Neil!

Graeme Harrold

I am afraid I have had to return these MR16 spotlights because they did not fit the fitting. I am exchanging them for similar but not quite so long. I have given them 5stars because of the build quality I have not tested them.

I had to return these as I did not realize MR16 lamps come in different sizes. Note that if you are fitting these into flush fittings like mine, they will stick out by 10mm. The COB lamps are 55mm deep. A standard halogen is 45mm. There was nothing wrong with the COB lamps, but I had to return them, and they have now been replaced by the MR16 SMD version which is 45mm deep. These don't seem quite as bright as a 50W halogen, but they are OK otherwise. They also have a 120 degree beam angle so the light is spread more evenly. I've fitted a total of 14 and have reduced the total power consumption from 700W to just 84W! Brilliant!!

Good down lighters, lovely warm light. Just as expected.

I installed 12 of these warm white versions in my kitchen to replace 35W MR16 lamps. I had previously installed four lower wattage (4W) LED in the same area and found the lighting just about OK but with less intensity (120° type) than the halogen lamps. Having fitted these COB 6W the light level is now very close to the halogen light levels and adequately lights the kitchen area. There is a difference to the spread of lighting with the old halogens being a smaller area and the LED's giving a wider area that is just perfect compared also to the previous 120° LED's fitted. The only problem I had was that the shape of these COB LED's on the edge of the glass face is recessed and different to the old flush face of the MR16 lamps. The spotlight has a metal clip that holds the lamp in and I had to bend these clips with pliers slightly, to allow the clip to hold the lamp in the spotlight. I can't see much point in going for smaller wattage lamps if you want a contender to match halogens.

i was told the warm white resembled a halogen light effect , If im honest i cant tell the differance betwen my old halogen light and this bulb when fitted and it uses less than half the energy! i am now a huge fan of LED lights and i will be returning to wholesale led lights as the service and the products are fantastic. thanks again.
