I have had several light meters over the years. I am currently using the Extech LT300 myself. I like the display backlighting feature that can be turned on when needed (on some of my surveys, it's so dark that you can't read the meter.) Its also quite rugged. What I don't like about this meter is the detached sensor head. It's tough to hold the meter, sensor, and try to write light readings on a clipboard at the same time. There is a tripod mount on the back of the meter, but IMO, it should be on the sensor head instead of the body of the meter.
I also have a Minolta T10A which was quite expensive (over $1,000). I thought spending more and buying a "professional" grade meter would give me better results, but that is not the case. This meter doesn't have backlighting and is quite fragile compared to the Extech. One drop on the pavement and this guy would be toast.
I got together with an electrical engineer one night to survey a big parking lot. He brought his meter (also a Minolta) and I brought my two and we set them side by side to compare readings. None of them matched - there was at least a 10% variation in readings between meters in the same spot.
I think that in our line of work, we are just trying to establish an order of magnitude anyway. Is the light on the order of 100 lux, 10 lux, 1 lux or .1 lux? For these reasons, I don't think that having a super accurate meter would give you much anyway.
Features I would like to see: Autologging feature with GPS coordinates, voice announcement feature that speaks the readings as I take them.
