This genuine Luminor RL-470 UV lamp is the standard lamp replacement for the Luminor UV unit model number LB5-062.
The 22W UV lamp gives a 30mJ/cm² dose at the end of UV lamp life at 1 year. This means that you will get slightly more when you turn the UV disinfection lamp on for the first time, and from there it will reduce downwards. After the year, it is not seen as being effective as a disinfectant.
The Luminor RL-470 UV lamps are fragile and the glass should not be touched, this is for the same reason as car headlights. The UV lamps run hot and the oil on your hands will mark the glass and create a weak point. If you have to touch the glass part of the lamp, you should wear gloves.
