PAR Meter; How to take the measurement and compare the results

Watch the video explaining how to take the measurement and compare the results.

Seeing is believing? You can test this Dimlux grow lamp yourself and compare it to the Philips lamp you are currently using. Place a PAR meter  under the exact center of the fixture containing the Philips bulb and take measurements after 5 minutes, 10 minutes and 1 hour. Then repeat the same test with the Dimlux DXO CA Spec lamp, and you will be convinced by its superior performance.
