Maxsisun MF 2000 Review

The Maxsisun MF-2000 is a nice mid-size quantum board style grow light. It has great components with Samsung LM 281b+ diodes and a Mean Well Driver. It also features a remote control dimmer, thick heat sink, and a reflector. It is marketed for 4’ x 2’ or 3’ x 3’ coverage, however, it does best in a 3’ x 2’ area. It has great usable photon efficiency up to 1.89 µmol/w, and it comes at an incredible price.

Maxsisun sells through Amazon and growers often lump them together with cheaper discount brands. However, they make quality fixtures and I appreciate that they try to market them honestly. Some brands on Amazon provide exaggerated and unreliable data about their lights. It is common to see inflated Photon efficiency numbers. But Maxsisun doesn’t play that game. Instead, they provide a credible Sphere Test Report and advertise an honest 2.1 µmol/w. 2.1 is a great number for a quantum board style light. Its not as high as some of the numbers published by competitors – but its also not made up. In my book, Maxsisun gets a lot of credit for posting legitimate PPF data.

The Maxsisun MF-series are full-spectrum, dimmable LED grow lights. There are two new models for 2021. I tested the MF-1000 and published that report and video in January 2021. The MF 2000 is a little over twice as powerful.

The Maxsisun MF series have aluminum reflectors, which define the look of the fixture. They look similar to other brands, but Maxsisun adds a separate heat sink. The ribbed aluminum heat sink on top of the reflector is an upgrade that prevents the diodes from getting too hot. Heat dissipation ensures a cooler operating temperature which leads to improved efficiency.

One notable feature of the MF series is the remote control. The remote control is required to adjust the dimmer. I would tether the remote to my grow tent to prevent misplacing it. It offers preset buttons for 10-100% in 10% increments. It is nice to have precise adjustments with 10 different dimming levels. As you can see in the chart below, the dimmer is accurate throughout the dimming range.

Maxsisun uses a top end Mean Well driver and Samsung LM281B+ diodes. The Full spectrum diodes are split between 3500K warm white and 5000K neutral white. They also include 660nm red and 730nm far red diodes. The total color temperature for the fixture is 4068K.

They use a total of 700 diodes, which is an impressive number for a fixture this size. With a listed power draw of 230 watts, it equates to over 3 diodes per watt. Some competitive fixtures have fewer than 2 diodes per watt.

I tested the Maxsisun MF 2000 first in a 120 x 60cm (4’ x 2’) test area, which is the recommended coverage area. At a height of 38.5cm (15in), the Maxsisun MF 2000 had a maximum PPFD of 1000 µmol/m². However, the average PPFD across the 8 square feet was only 571.1 µmol/m². The area is just a little too large, and as a result the photon densities at both ends of the canopy are below the target threshold of 500 µmol/m².

In the 4’ x 2’ test, the Maxsisun MF 2000 delivered a usable PPF of 411.2 µmol. I measured a power draw of 218 watts at 120 volts from the wall. That gives the MF 2000 a Usable Photon Efficiency of 1.89 µmol/w.

Prior to testing the MF 2000, I ran the Sphere test numbers that Maxsisun provides through our Grow Light Calculator. The calculator’s estimates and my measured results are within 1%. With about 411 µmol of Usable PPF, the calculator suggests a coverage area of 6.3 square feet. So, I decided to run a test in a 90 x 60cm (3’ x 2’) area.

In a 3’ x 2’ area I hung the MF 2000 at 40.5cm (16in) above the sensor and recorded the maximum PPFD at 1000 µmol/m². The Maxsisun MF 2000 is able to fully light this space. The lowest PPFD was up at 543 µmol/m². In this test there was an even spread of high-density light from corner to corner.

In the 3’ x 2’ test, the average PPFD is excellent at 729.8 µmol/m². That converts to a Usable PPF of 394.1. The Usable PPF is only marginally lower than the 4’ x 2’ test. Of course, the Usable Photon Efficiency is also slightly lower, but it is still 1.81 µmol/w.

With their remote-control dimmers, both MF series fixtures will also work great for seedlings, clones and mothers. The MF 2000 can power a 4’ x 2’ tent through to a good harvest, but it will perform the best in a somewhat smaller space. If you want to fully light a 4’ x 2’ tent, I would consider running both an MF 2000 and an MF 1000 side by side. That set up would give incredible coverage, efficiency, and flexibility.

The most impressive statistic is the cost efficiency. The normal price for the MF 2000 is about $240, but we have a 10% discount codes for the MF series that are good on Amazon. Use code: mf1000coco when you shop for the MF 1000 and use code mf2000coco when you shop for the MF 2000.

With our discount the MF 2000 will cost only $216, which is only $0.53 per micromole. It is among the most cost-efficient fixtures in its class. Considering the quality and efficiency of the Maxsisun MF series lights, it is an outstanding deal.

If you need a small light for about 6 square feet, the Maxsisun MF 2000 is an incredible value. It has top end components, over 3 diodes per watt, gets good efficiency, and it will light up 6 square feet with excellent density. At $216, it’s a great deal, but even better – I am giving this one away!
