Everything depends on which model and features really
"Old" Apogee (needs computer, win or Mac OS) is $234.
Advantages.. cosine corrected, software may be more flexible
Disadvantages: Not a "perfect" sensitivity i.e high end cutoff is around 660nm
PAR (photosynthetic active radiation) is the easiest way to measure the available light for corals consume and use for photosynthesis. With LED lights giving more and more control to the consumer the best thing is a PAR meter that is affordable and simple to use. With PAR readings you can...

Seneye Reef $219
Major advantages: Has Ammonium and nitrate cards (bit pricey) temp sense, phone/email alerts.
Disadvantages: Directional readings (no cosine correction), not a perfect sensitivity but about the same as above.
May still need a Win computer

Point of the above is each has features and usability functions the value of which depends on the users needs.

Also the Apogee line is more expansive from hand held meters and/or better sensitivity curves and extended nm ranges.
The SQ-616 smart extended photosynthetically active radiation (ePAR) sensor can be connected directly to a computer to take spot measurements or graph and log real-time PFD using the included software.
