Ok bought this instead of oyher yo support us company' photone app on my phone is within .2 accuracy to the meter! Thats a hard pill to swallow! Not wotth 400, 325.00! It was fair priced at 200.00 now its just a better option to go with apogee' way better build quality' this feels like a kids cheap toy.. not impressed yal.at 400 i work for that money!

If you need to get accurate PAR readings for your grow room, this is the tool you need.The device doesn't take up much space and its fairly easy to use.It will tell you how much photosynthetic energy your plants are getting from either the sun or your current lighting setup so you can make adjustments as needed.So far its been providing quality measurements that are consistent and reliable. Very helpful for making adjustments to setup and getting optimal results with what I have.RECOMMENDED>

I use this meter to monitor bulb life and overall I am happy with it. It has a inexpensive feel to it, not cheap just inexpensive. While it works good I think the price is high considering the build quality. 4 STARS

The media could not be loaded.  Absolutely brilliant.A lot of these meters do not work on LED and that's like having a shotgun that doesn't work on deer. This device is wonderful for determining which LED fixtures are the best for my needs. I've been pretty shocked a couple times when the more expensive LED boards are weaker than the less expensive. It's incredibly simple to use. No instructions necessary. This light meter even came with Is an extendable wand for hard to reach places.Overall it's a must have, in my opinion for any indoor Gardner.I definitely recommend it!
