The LUMii HID Reflector Extension Lead is available in 1.5m and 5m lengths. Suitable for use with all LUMii and IEC reflectors. Please make sure that when you are using extension leads for HID, your ballast is built to ignite the lamp over long distances. PowerPlant and LUMii ballasts are able to ignite a lamp from up to 15 metres from the ballast.
