Reptile Systems’ Mercury Vapour Lamps Not all brands of mercury vapour lamps are equal in terms of build quality and UV output. All Reptile Systems mercury vapour lamps are triple checked; firstly, at the manufacturing stage, each lamp is plugged in to make sure they’re working and the UVI output is checked. This is to ensure the output fits the guidelines that Reptile Systems set for their products. The product is then shipped to their German partners where it is switched on and the UVI checked again. Once checked and passed the product is etched and boxed before sending to France which is where Reptile Systems headquarters are based. A box from each batch is sent to the UK testing facility to make sure the lamp is working and the UVI checked again! Once passed for the 3 rd time the lamps then go on sale. All the lamps are tested in Reptile Systems’ large UK testing centre where they have over 200 lamps on test at any one time. Lamps are checked to meet multiple parameters making sure that they reach the high standards.

Safety features built-in to the lamp, protect it against wide voltage fluctuations and overheating. If your lamp doesn’t switch on after a power cut or if you have turned it off, we recommend allowing it to cool for 20 minutes before turning the lamp back on again. This is a common occurrence with the technology in mercury vapour lamps. If you live in an area prone to voltage variations, your lamp may flicker. We always recommend surge protectors to be used with all electrical products.
