Typically $350 to $1,100. You might want to look into borrowing or
renting such a meter.

You would think that China would have some for way under $50 . While
they may not work the best, China seems to have almost every thing else
very inexpensive.

Bad to pay $ 300 + to check out a $ 20 or so light.

I couldn't find anything from China that is substantially cheaper:

The bulk of the cost seems to be in the sensor and the UV-C filter.
