More Light & Efficiency - Grow Bigger With The Maxibright LED Daylight Pro Grow Light 

In terms of 'price versus performance', the 660w Maxibright LED Daylight Pro grow light is one of the best LED grow lights we've tested so far. It is incredibly efficient and produces an incredibly even footprint, and utilises highly efficient diodes meaning the fixture has an output level of a whopping 2.7 μmols per watt!

It is ideal for a 1.2m x 1.2m grow or even a 1.5m x 1.5m grow space. More light and less heat means your crops will be bigger than ever before!

How the 660w Maxibright LED Daylight PRO Grow Light Works

Having tested ththis unit, Maxibright have wisely chosen to adopt a "spider" design that matches the latest generation of LED, like the Gavita 1700e. Instead of concentrating diodes in a central spot and using lenses to direct the light outwards, Maxibright have opted to spread the diodes over a much wider area, using six separate strips. This allows it to deliver a footprint that's much more even than that of a regular HID lighting system or "module" type LED grow light. On top of that the fixture efficiency of 2.7 µmols/Watt blows HPS light efficiency which is, at best, only 2.1 µmols/Watt

This unit has been designed so that it's easier to transport than similar alternatives. For this reason, you'll need to assemble it when you receive it, which can be done comfortably in 5-10 minutes. This means that you can get it through tight spaces like loft hatches. It comes in a box that's easy to transport and store, and it won't require a pallet delivery.

It emits intense levels of red light that will cause fruits to swell up in size as you progress through the flowering stages. Naturally, the unit is full spectrum, so there's also a very healthy level of blue in there to keep the stretching down and optimise the quality of the crop. There's some far-red too which stimulates the flowering / fruiting process. You can see the superbly optimised spectrum on the about section.

  • Osram Red LED efficiency: 3.8 µmols/Watt
  • Lumiled White LED efficiency: 2.85 µmols/Watt
  • Combined LED efficiency: 3.15 µmols/Watt
  • Fixture efficiency with driver: 2.7 µmols/Watt
  • PPF Output: 1782 µmols/Second

Maxibright Daylight Pro 660W LEG Grow Light Spectrum



Maxibright Daylight Pro 660W LED Grow Light

The Maxibright Daylight 660w LED Grow Light system offers a perfect footprint for maximum plant growth. Its passive cooling technology allows the unit to put all its efficiency into its light output. The LED bars are arranged in a spider footprint and it's one of our favourite footprints. The Maxibright Daylight 660w LED also has a really high chip efficiency of 2.7umols per watt, giving you a fantastic full spectrum LED which has an unbeatable output. Once you do a full spectrum LED grow, you'll notice the quality increase!

How to use the Maxibright Daylight LED 660w Pro Grow Light

The first thing to do is to clip in the six LED strips into the main body making sure to open the grey clips on each bar before trying to mount them to the main unit.

They clip on the provided hangers to each end of the ballast on the mounting hooks provided. The Maxibright LED Grow Light can now be hung by the loop in the middle of the hanging wires. You should note that, at 11.2kg, it's not the lightest unit, so you'll need to make sure that you secure it properly. The unit is a bit too heavy for hanging with easy rolls. Instead, we recommend rope ratchets or jack chain.

Next, use the power lead to plug the unit into the mains and switch it on. Check that all the bars are lit. If any do not light up then double check that the plug for those bars are plugged in the right way around.

The unit can now be dimmed to the desired level by turning the dimmer knob.

The Maxibright LED Pro Grow Light is designed to be used over a 120cm x 120cm or 150cm x 150xm square growing area. In this situation it offers an incredibly even footprint. We found that 60cm above the canopy is good for veg but for small plants you might want to begin up to a metre above the tops of the plants and reduce the height gradually over the course of a week or two. If you see any signs of stress (leaves hanging down as though they were wilting) then raise the light up again.

For flowering, we found that 45cm - 55cm is about right. Experiment a little to find the right height for your strain for best results. We've had customer feedback stating that they can get this grow light light extremely close (less than half a metre) to the top of the canopy, but bear in mind, this depends on the strength of your plants. We'd recommend using an infrared thermometer and keeping your canopy at 26 degrees for optimal results.

Size: 1120mm x 1160mm x 100mm
