Greetings from Gyeongju, Korea! Licor 1800 series if the club can afford it. It is probably the gold standard. The Apogee is probably a reasonable meter and I'm sure much more affordable. Be careful with these meters, though, as they have response characteristics which don't give accurate measurements as the spectrum get more in the blue range. Actually, Jeff is probably the resident expert on this type of scientific equipment.
