Hi, is it possible to aquire an effective low cost "germicidal lamp"? They seem like a specialized item used in the lab and hospitals and likely to be faked. I was thinking about a project with one mounted over the kitchen sink. Let me know what you think. Good day.

Germicidal lamps produce a damaging light. Having one over the sink is a recipe for disaster. They are best placed in an air stream such as a ventilation duct so that they don't emit their rays to human or animal flesh. UV-C is what you're asking about; and No, I wouldn't recommend putting one over the kitchen sink. Even if you shielded the light from flesh, hands go in the sink and light reflects off pots and pans as well as dishes and silverware. It's a bad idea overall. One I would vehemently advise against doing. They can damage eyes fastest of all flesh - as far as I know.

A uC would operate it at time when no one is near and I would monitor it closely. My concern is purchasing a genuine lamp as I am unable to verify the particulars (spectrum, range etc.). Placing one near ventilation ports is a good idea too. If the effect really does work, I wonder why I don't see them everywhere as a passive sanitizer.

How did your plan pan out?

My kitchen sink is not full of germs so I do not need a sanitizer. The sink is simply cleaned every day. My cleaning product is not a sanitizer.

"PAN" - Love it!

Looked into the link @Tonyr1084 provided. Looks a little promising but at the same time it looks like a bit of work. I'd have to put a heat sink inside a glass tube and find a way to draw the heat from the sink to the glass. I wish I could find that older lamp. I just have to tear the world apart and find it. I'm sure it's around somewhere.

As far as how it panned out - I haven't gotten much response so I haven't really formulated an approach just yet.

I recall buying easily a small tube plus the necessary ballast for erasing my first PIC micros (16C57).

There are incandescent germicidal bulbs; I used one as an EPROM eraser (with a 40 watt incandescent bulb in series as the ballast). You can buy various types of name-brand bulbs from specialist lamp distributors.

The ones I have are fluorescent bulbs. And they burn out too quickly. Given the nature of my pond - it's not an easy venture to replace the lamp. Hence the desire to modify it to be a UV-C LED lamp. Tony's link has me interested.
