Omega CMH 315w Review

As you can see in Shane’s Video above, this bulb and fixture were tested along side several other CMH bulbs. The fixtures were all tested in a 120 x 120cm (48 x 48in) area, which is larger than our testing protocol prescribes for this fixture. The larger testing surface likely increased the measurement of Usable PPF. However, the fixture was hung at a standard height of 60cm which is higher than our protocol suggests. The higher hanging height decreases the measured Usable PPF. These two factors largely offset each other and the measured Usable PPF from Shane’s test aligns with data from integrated sphere testing of similar CMH fixtures. The larger test area and higher hanging height are also responsible for the low PPFD readings, especially at the edges. When we have the opportunity, we will test another 315w CMH fixture following our new Grow Light Testing Protocol.

For a small HID fixture, CMH are more efficient than HPS and they offer the advantage of a better light spectrum for Vegetation and Flowering. However, CMH and other HID lights are less efficient than the LED fixtures that we recommend.
