Recommended light meter for LEDs under $150

It doesn't have to measure the whole range. You can calculate a conversion factor for the spectrum you are using and based on that you can concert the lumen value to a PAR value. That's actually pretty accurate. I'd be very surprised if a cheap PAR meter would be more accurate than simply dividing the lux measurement by say 69 (depending on spectrum).

Those cheap PAR meters are very inaccurate in anything but sunlight. So you will only get some baseline figure from those.
