Normally amalgam lamps costs more than normal low pressure lamps at here, as higher UV output does create a good return eventually. Furthermore, amalgam lamp has longer lifetimes due to inherent variety of the lamp itself, electrode design and internal protective coatings. Amalgam lamp lifetimes nearly 12000-16000 hours are sometimes achieved, maintaining an end-of-life UVC creation of 85% with operated with a preheat ballast.

this is a type of problem with many submersible UV Sterilizers (including the Pond Master) likewise, the 1st generation internal Aquarium UVs.
A blown filament is generally a dead giveaway for this problem, which may occur in virtually any UV found in water applications.If your UV Sterilizer is blowing filaments, I suggest washing the UV cautiously and inspecting for moisture. If no moisture can be obtained, likely your electronic ballast has shorted because this will also produce a blown filament.

To prevent this matter, always place your Pond UV within an area where it really is shielded by way of a stone or some other cover, it doesn't matter how weather proof your UV Sterilizer manufacturer may claim it can be.For Aquariums, ensure that your UV will not be right beside a sump where moisture can certainly cause a problem. One case for me personally when cleaning a clients aquarium, I accidentally spilled water from canister filter in the UV Sterilizer causing a temporary short that blew the UV Bulb.

LED systems can be found in a number of configurations according to the manufacturing process and coating material. One effective configuration involves arranging two LED systems, with focusing lenses facing the other, to attain a uniform UV intensity on the fiber. Because UV LED systems might be arranged within a lens-to-lens configuration, no external reflector is necessary, which saves additional costs and downtime as compared to lamp-based systems. The current UV lamps also call for a higher infrastructure cost as a result of ozone production. Radiation of wavelengths a lot less than 200 nm generates ozone from oxygen in mid-air. UV arc lamp systems which generate light below 200 nm produce ozone that must definitely be filtered and vented facing outward with an exhaust system for 800W uv lamp ballast . Production facilities, which must mould to EN14001 requirements, include costly stacks and scrubbers. The narrow-spectrum UV LED curing systems don't produce light below 200 nm, and therefore usually do not generate ozone, eliminating the requirement for external venting. This further reduces operating costs and simplifies compliance with environmental standards.
