OR should I be looking at other models??

It would be good for a reference, as in installing new lamps & comparing the new readings to old readings, etc. for the price unless you want to get into the buks.

 

[NC2WA]

Scooty,

What does the "buks" get me that this model would not??

it mainly would be used for a periodic check of PAR values.

 

[Crystalclear125]

this doesn't measure in par only lumens ...
sorry par meters are super spendy..

 

[Scooterman]

Compare with theses. Is it necessary to do what you want, IMO no, you can do it with the one you picked out. All your doing is using it for a reference right?

Actually If you look at sanjays light comparisons your looking at ppfds

Few more for the poor man LOL

I've got the Apogee Quantum meter...it's pretty cool. I did some digging and found that it's spectral reponse for bluer light can be off, but it's definitely a good meter for getting fairly accurate PPFD readings of PAR. Certainly not cheap compared to the device you originally asked about ($300), but it will set you back much less than the Li-Cor meter.

Scooty,

You are killing me with all the reading.

Reminds me of the days of college when had to read couple of chapters a day for biology.

Will start reading tomorrow and chime in if I have any questions.

thanks again

Scooty,

OK, what the heck is a footcandle? Some units measure in Lux and footcandles??

You know how some lights like flashlights are rated in candle power. Same kind of thing just a different scale.

 

[NC2WA]

No, that is new to me too...candle power, footcandle...when it comes to flashlights, I just put batteries in and want a light to shine...LOL...

Ii is a measurement in a foot of radius, just another mathematical way to measure light, I think photographers use this most.
