Converts your G24 4 pin holders to take a lamp with an E27 base. In doing this you may need to bypass any control gear.

You will need some rewiring for this adaptor to work. The original 2 pin lamp runs from a ballast the ES lamp you will be using in its place will run directly from 240v.

To ensure your replacement 240v lamp runs correctly the fitting will need to be rewired and the ballast by passed so the holder is connected directly to the mains.

If you are unsure about this procedure then we recommend contacting an electrician.
