What’s the Problem with LED Lighting?

In early 2014, Which? magazine published a review of LED bulbs sourced from popular high street brands and the results were not impressive. We at JMG LED Lighting have been working with LED Lighting since 2005 so it was very disappointing to see a technology which should be being readily adopted by both domestic and business customers receiving such bad press.

So what’s the problem with LED Lighting?

Essentially there’s nothing wrong with LED lighting but we are dealing with quite complicated technology – the images below shows the interior of a typical LED bulb. LED-Bulb-Interior-1LED-Bulb-Interior-2Many people don’t realise just how much electronics are required in the design of a humble domestic LED bulb (and why should they – all the customer wants is light!), but it is this very technology that the cause of reported problems occur.

We are all looking for “Value for money” and the pressure on manufacturers to reduce the price of LED bulbs has been enormous. Many manufacturers respond in the only way they know by looking for cheap components and occasionally making dangerous shortcuts in the design.

It simply requires a manufacturer to purchase some cheap capacitors or cheap drivers (the transformers which drop the voltage from the 240v AC in the supply to the DC voltage required by the LEDs) and the entire bulb becomes at risk of failing in the short term.  One of the manufacturers we buy from pay more for the drivers in their bulbs than they can buy entire bulbs from some sources!

So, what are we saying?

It’s the old story…..you get what you pay for. If you buy cheap LEDs, you’re running the risk of buying products which have been subject to the compromises described above. We use Crompton Lamps as one of our main suppliers of domestic LED bulbs and they have been manufacturing lighting for decades.


Good shopping!




How to convert a 12v/24v bayonet light fitting to an LED

How easy is it to convert a traditional light fitting to use an LED bulb?

The answer, thankfully is that it’s very easy nowadays. The photograph below shows a very popular light fitting which ordinarily uses a 20 watt incandescent bayonet bulb but which has been converted to an LED equivalent which uses only 2.5 watts – a saving of 17.5 watts EACH HOUR!

All that’s been used is an adaptor which has a bayonet fitting on one end and a G4 fitting at the other end, into which you place an LED bulb.

Using these adaptors gives you complete control of the power of the LED bulb and whether you want Warm White or Cool White LEDs.

LED Bulbs to exchange for Halogen Bulbs

The same principal applies if you have a light fitting where the bayonet bulb fits in sideways into the unit. In the following image, the same adaptor has been used and the end of the adaptor twisted around until the side fitting LED bulb pointed in the desired direction. (Make sure you take the bulb out before you twist the end of the adaptor…..or you’ll just pull the pins off the bulb!)
