Can I make my light double insulated?


Can I convert my light to double insulated?


Occasionally we are asked if a persons’ light fitting can be converted to double insulated. Usually an electrician has removed a beloved old light that has hung in a room for years to do some routine maintenance and discovered that the house has no earth connection & the beloved light can’t, according to current electrical regulations, go back up again. The electrician will advise the client to purchase a double insulated light from someone like Lightahome or to rewire the houses electrics, which can be costly & messy.

A light is double insulated by the way it is wired and manufactured. If an issue occurs within the light then any loose wiring cannot touch the unit because all connections are insulated. This is why a double insulated light can be made of metal. Why then can’t an existing light be converted to double insulated? In theory it shouldn’t be difficult. There are issues however.

A double insulated light is tested thoroughly & given a safety certificate which is only cost effective when manufacturing thousands of units


All double insulated light fittings are manufactured to stringent regulations. A manufacturer will produce a light that is double insulated and that light will have to go through thorough testing by the relevant authority to confirm the light is safe and is compliant with electrical regulations regarding class 2 double insulation. This will cost the manufacturer a very large figure to test the product and have it approved. This is cost effective for the manufacturer as they will produce thousands of the light over its retail lifetime. This cost can be built in to the products price and might only add a few pence per unit over time.

It is not, however, cost effective for a single light to go through that process. The light you would like to convert will also have been issued with a safety certificate based upon its original design. Once you try to convert it you are changing the material makeup of that light. Not only is it costly to have it tested (in the thousands) but also actually finding someone to actually do that testing would be practically impossible.

Having an electrician add an earth wire to a light is the only real way to continue using your existing light if you don't want to fit new double insulated lights


Converting to double insulated is not a normal approach in the lighting industry. On the occasion where we have been asked to see if it’s possible or if we have any advice then the client has always either had to change their lights or on occasion they have worked with an electrician to find a way to get an earth wire to the light and back to their consumer unit (fuse board).

So, to sum up it’s not really practical to convert an existing light to double insulated due to costs and availability of a relevant person willing to attempt it. If you really desperately want to continue to use your existing light then you will need to see if an electrician can add an earth wire to your light or have all the lighting in your home rewired. If both of those are not an option then you will need to replace your existing lighting with double insulated lighting, which is available on Lightahomes’ website
