An Electrodeless Bulb for Consistency and Long Life


Powered with microwave energy, and without the metal electrodes required in arc lamps, the remarkable high-grade quartz UV bulb from Heraeus Noblelight America is fully guaranteed to last 8,000 hours, with an even longer lifetime reported by many users. 


Easy to handle and quick to install, it only takes three minutes to change the bulb. We use a unique microwave excitation system to energize the lamp for very rapid starts and restarts, and very stable spectral and energy output. Bulbs with different spectral outputs (only Preferred Visitors can access these) allow you to match to your changing chemistry and applications for improved quality and cure speeds to Heraeus Noblelight America's lamps.

Other Helpful Information 


How do I tell if a bulb is bad? 


How should I clean the bulb ... and the reflector? 


Disposal of UV bulbs should be by the same approved method as for fluorescent bulbs. State and local regulations apply, so determine what they are and what your responsibilities are. In July 1999, the EPA adopted less stringent requirements of disposal to encourage "compliance with hazardous waste requirements.” Most large users of fluorescent bulbs deliver them to a hazardous waste contractor. Any safety or disposal regulations that EPA or OSHA applies to fluorescent lamps also apply to UV lamps. Heraeus Noblelight America accepts used bulbs for disposal if they are sent in appropriate protective packaging at the customer's expense.
