Completed and powered on.
Very little UVC light output.
Stupidly, I ordered a ZWB1 filter, whereas this UVC lamp requires a ZWB3 filter sad
So, another few weeks wait until the correct filter arrives.

Ooops BW...

That's a bright torch Sand Surfer... I think you will find the 'UV' is a 'Black Light'..... Ok on some minerals but not in the UV Spectrum...

That would be good in the bush at night tho. Lots of Fun.. big_smile

We plan to build a 'Home use' UV light first... then move into the Field Lights... They will take a bit more to get up and going... But they won't be as expensive as most that are out there...

You could always use a generator to power a home light in the Field... That would work in most areas that I know where these minerals hide... pickshovel

It would be interesting to see if performance was changed at all in a meaningful way later on with the use of a fan regardless of heat issues. Some/many bulbs create ozone which strongly absorbs UV-C so it's best to vent it out if it's in there. I guess a sniff test would tell you if a lot of ozone being made.

You were quite correct Guessologist and I thank you for your input.

The lamp that I bought does have a 10% 185nm spectral omission, which creates a lot of Ozone.

These 254nm germicidal lamps come in Ozone and non-Ozone variants (the non-Ozone variants use a Chemical doping of the Quartz to suppress the 185nm emissions).

I'll start looking for a non-Ozone emitting lamp such as the Philips TUV PL-S series.
