Should I use LED, Halogen or Incandescent lightbulbs in my double insulated light?

Should I use LED, Halogen or Incandescent lightbulbs in my double insulated light?


So, you’ve already got over the fact that you don’t have an earth connection in your lighting circuit. You discovered you can buy double insulated lighting from Lightahome and your electrician is happy with what you’ve bought. You’ve banged the kettle on and are enjoying a celebratory cup of tea, happy that peace has been restored to the galaxy. There’s nothing else to consider and all you need to do is wait for the new class 2 light to be fitted. Or is there? Should you be considering what type of lightbulb to now fit in your new light and will it really make a difference? Well actually yes it might just do.

The first thing to understand is the four types of common lightbulb that is currently used and what the differences between them are. If you’re old school, you will love incandescent. You know the ones, with their filaments burning and slowly being phased out by EU regulations. Then followed by their halogen cousins which arrived all bright and in your face. Once we all realised that ‘maybe we were all using a bit too much energy’ we had CFL lightbulbs (compact fluorescent) which was the bright new thing. Once we all got fed up of waiting for these bulbs to warm up when we switched our light switches on those clever manufacturers introduced LED lightbulbs.

It’s safe to assume that CFL bulbs are now off the table as they have been fully replaced by LEDs which do the job much better. As a lighting retailer we have seen the collapse of CFL bulbs by the manufacturers, so we’ll consign these to the great big lighting heaven in the sky and focus on the incandescent, halogen & LEDs.

Now we know everything there is to know about lightbulbs (ok maybe an exaggeration) we need to understand something about class 2 double insulated lights. Obviously as we have explained before, a class 2 light is designed in such a way to be safe should an issue occur with your light. Obviously without an earth connection, there isn’t anything to remove the danger if, for example, a wire comes loose and then touches the material of the light fitting. These specialist lights are designed in a way so that their wiring protects this from happening, but wouldn’t it be even better if the threat of this happening was even further reduced? Well yes obviously but what has the type of bulb you choose go to do with this?

Well, speaking as a person involved in the lighting industry, I can confidently say that the one thing that has a massive effect on the health and life of a light fitting is heat. Heat bakes a lamp holder. Take a look at an older light and look where you put the bulb in. Chances are it’s a brown colour. Chances are the wires are a bit brittle. Years of sitting next to a hot bulb takes its toll on the delicate components of a light. Imagine how you’d feel! Seriously though, it’s no coincidence that all these older lights have been working away during a period where incandescent and halogen light bulbs have been the prominent type of bulbs to use. Have you ever been near a halogen GU10 lamp? Seriously, don’t even try it! They are red hot. As are the incandescent lightbulbs. Both create a massive amount of heat, easily hot enough to burn you badly. Ask your parents what it was like when you tried to change an incandescent 60w lightbulb before it had cooled down enough!

Heat is a massive issue with the reliability of a light fitting

It isn’t rocket science to work out that something like a double insulated light, that is designed with safety in mind, doesn’t really want something red hot burning inside it. This is where LED lightbulbs come in. LEDs don’t emit any heat. You can touch an LED GU10 bulb when it is on and it is stone cold. Put LEDs in a light fitting and you won’t get any baked lamp holders or brittle wires. Let’s face it, you’ve fitted a double insulated class 2 light because firstly you have to but secondly because it’s safer. Why not make it as safe as you possibly can by fitting a cold LED bulb in it. The prices of LED lamps are reducing rapidly and the quality of light output only gets better and better.

So, in answer to the question of this blogpost, what type of light bulb should I be putting in my double insulated light, I would recommend an LED wherever possible. It will cost you less to run, last longer and more importantly, will keep your double insulated light safer and extend its life.
