Absolutely, Al! Measuring visible light is inexpensive and relatively easy. But measuring UV light in a museum setting (needs to be in micro-watts per lumen), as opposed to cheap sunburn meters, is a different beast. My Hanwell UV meter designed specifically for museum applications cost $1,700 for example, and there are not any that are suitable for museum purposes that are much less than that. My study was of inexpensive visible light meters costing less than $35. BTW, to convert from lux to foot-candles, simply divide by 10. This is not exact, as the actual number is 10.? but it gives a good enough approximation except for the most critical applications. So if a reading is 150 lux, it is 15 foot-candles. Or if it is 50 foot-candles, it is 500 lux. No need necessarily to have both scales on a meter.

Makes a difference in the kind of meter you buy.

Are you just wanting general readings with sunlight/daylight involved, or are you wanting very precise readings inside a display case with sensitive objects? Is the light natural daylight or incandescent or fluorescent?

I am wondering if anyone has purchased one and has any feedback or recommendations? I wonder if there are models that measure using different units, such as lux, lumens, footcandles, et cetera?
