Product Details

Buy this kit and create your own 9 watt UV-C germicidal lamp. If you're familiar and comfortable with 120 volt AC wiring then it should take you only a few minutes to wire it up. A wiring diagram is included. To plug it into the wall you will need a lamp cord with an AC plug on the end. An old extension cord would work fine.

The bulb in this kit has an output peak at 254 nm which is highly effective for germicidal applications. The bulb does not produce ozone. It has a special coating to block the ozone producing radiation. We test and measure the UV-C output of each bulb before shipping.

The plot below shows the output spectrum of the bulb. 90% of the radiant power is at the germicidal wavelength of 254 nm.

Assembly and use of this kit requires knowledge and experience in 120 VAC power wiring. Incorrect wiring can cause fire, injury or death. Wiring diagram is included with kit.

Replacement bulbs are available.

WARNING: The UV-C radiation put out by this bulb can cause skin and eye damage. Exposure should be limited as much as possible. Never look directly at the bulb when it is on. When sterilizing a room, people and pets must not be present.

Free email support included with purchase.
