How can you get the most uniform distance from an LED bar light? How much light is lost as a grow light is raised or lowered? After unboxing, I tested the PAR levels of the Maxsisun MG3000 to see how it can be configured for various growing applications. After taking over 800 PPFD spot readings with my Apogee SQ520 sensor, I've compiled the results of my testing for this video product review.

The MG3000 is a perfect fit for a 3ft x 3ft or 90cm x90cm grow space. It can be hung 12", 18" or up to 24" above the plant canopy in a 3 foot tent. The chassis is structurally reinforced to withstand up to 140 pounds of weight. It's a solidly built light as demonstrated by my "step test". The light comes fully built with no assembly required. It has a quality feel and the light output and spread is excellent.

PRODUCT HIGHLIGHTS
=================

• LIGHT OUTPUT: The Samsung diodes & Mean Well driver are good quality. Not the premium topoftheline. But still very efficient, at an affordable price. Maxsisun properly tested the light & posted their integrating sphere test report in their site. At 289 watts it outputs a PPF of 687 umol/s which translates into an efficiency rating PPE of 2.38 umol/J.

• LIGHT COVERAGE: The PPFD maps provided by Maxsisun were taken with an Apogee MG620 light meter. This meter cover a broader spectrum than standard PAR (400700nm). So I took my own readings with the standard Apogee SQ520 sensor. In my test bed, I observed excellent light coverage from the center to the corners. For a flowering 12/12 cycle, this light is ideal over 9 sq ft. It could cover 16 sq ft for seedlings, clones or vegetative growth.

• HANGING HEIGHT: I recommend a minimum of 12" or up to 24" in a 3x3 tent. You might go a little higher in a 4x4 tent for low light applications to achieve optimal light spread. Compared to 18", you can get a 4% boost in photon output by lowering the light to 12". But this comes at the expense of uniformity in coverage. For the best coverage from center to corner (in a 3x3 tent) try raising the light to 24". Be aware that the photons hitting the plant canopy will drop by 5% though.

• DIMMING: The dimming function predictably reduces light levels. Expect a 50% reduction in power (wattage) to reduce light output by 50%. Note: The dimming knob cannot be relied on for accurately achieving your target brightness. Use a KillaWatt meter to check power at the wall or a light sensor to achieve your target brightness at the canopy.

• FINAL THOUGHTS: Maxsisun's MG3000 is an excellent option for entry level medicinal growers, but also for hobby gardeners. It can easily replace a 400W HPS light. Or even up to a single ended 600W HPS. But a double ended HPS in a modern ballast will have higher output than this LED. It's an option for T5 fluorescent users. This 289W system can replace a 12 bulb, 4 ft T5HO fixture, which would normally consume 648W.

The MG3000 was a good value, but due to stock issues I now recommend the Mars Hydro FCE3000. See link above!
