Blue light bulbs have the advantage of releasing less heat. For best results, polymerisation units should be regularly checked, ensuring the fibre-optic is in good condition. Lamps need to be replaced every 3-6 months (depending on level of use) to avoid a reduction in performance. To ensure the best results, it is imperative that the lamp is exposed in 400mw/mc² and is left for 10-20 seconds in between 400 and 500nm. If this is not done, the results will not be satisfactory and will have a harmful, non-polymerisation effect. Suitable for: Siemens Sirolux S24 V, Fantastic, Volts: 24, Watts: 150.
