What Are The Maxibright Daylight 660W / 660W PRO Full Spectrum LED Grow Lights UK?

The new full spectrum Daylight LED technology grow lights from Maxibright are high output units that push the envelope for plug-and-play LED grow lights. A superior fixture efficiency works to improve final yields.

Maxibright's 660W and 660W PRO Daylight LEDs feature an updated, streamlined and lightweight design. The new Daylight LEDs are full spectrum LED grow lights UK. They introduce improved clip on bars, making them easy for one person to assemble.

This awesome full spectrum LED grow light offers a full-bodied PAR spectrum for improved plant growth. The high total output of this quality LED grow light combines with the ladder design to offer an even spread of light. It allows you to position the LED light fixture closer to the canopy. Instead of using lenses, the Daylight LED outperforms traditional HPS grow lights by using a ladder design to evenly spread light from individual chipsets over the unit's footprint. An even spread of light avoids hotspots, which allows closer mounting to the canopy, helping to improve final yields.

Maxibright Daylight 660W / 660W Pro LED Grow Light Benefits

The many benefits on offer from the Maxibright Daylight LED grow lights are convincing even the most hardcore HPS growers that switching is more than worth the investment. LED grow lights saving money in the long run as they produce less heat. LEDs waste less electricity to heat.

Maxibright Daylight LED 660W / 660W PRO Grow Light Fixture Efficiency

Six bars of high-efficiency Osram and LUMLED LED chips uniformly illuminates a 1.5 m x 1.5 m growing area. The higher quality par light works to out perform HPS grow lights Watt for Watt. The following PPF and fixture efficiency figures highlight what these awesome LEDs have to offer your grow tent:

  • The 660W PRO LED grow lights exhibit a class leading PPF of 1782 μmol/s and fixture efficiency of 2.7 μmol/J.
  • The 660W LED grow light exhibits a PPF of 1518 μmol/s and fixture efficiency of 2.3 μmol/J.

660 W Pro 660 W (Standard)
  • LUMLED white (2.85 μmol/J)
  • Osram red (3.8 μmol/J)
  • Total PPF 1782
  • LUMLED white (2.6 μmol/J)
  • Osram red (3.15 μmol/J)
  • Total PPF 1518

A fanless, solid-state design provides silent operation and eliminates the risk of mechanical failure. High-quality components and passive heat dissipation, teamed with the ability to dim the units to 25% power, allows you to flexibly control grow room temperatures in any weather.

The unit is supplied with a free dimmer to allow remote control of the unit from outside the growroom.

An IP65 ingress rating protects the unit from high grow room humidity levels. An LED lifespan rated at >50,000 hours and 3 year warranty supports your buying decision and makes this LED grow light a worthy investment.


Ladder Style LED Bars

The Maxibright Daylight 660 W LED grow lights use as much power as a traditional 600 W HPS on overdrive, but produce much more light, which shows with greater final yields. Instead of using lenses, the Daylight LED grow lights use a ‘ladder’ design to evenly spread light from individual chipsets over the unit's footprint. The even spread of light avoids hotspots, which allows closer mounting to the canopy to improve your yields.

Ladder style fixtures are well suited to vertical farming methods due to their low profile and low heat output. This style of fixture is increasingly popular among commercial, large scale operations, particularly in the USA.

More Flower Using Less Power - Advanced LED Lighting Technology

LED lighting technology has evolved at the speed of... well, it's come on leaps and bounds over the past few decades. As the technology has progressed, so have your performance expectations.
