Maxspect R420R 320w LED Module - 15000K

Maxspect R420R 320w LED Module - 15000K

Discontinued to be replaced by the all new RSX.

The Maxspect R420R LED Module 320w 15000K redefines the term efficiency. With temperature controlled cooling system, utilizing highly efficient high intensity LED chips from Cree, e.g. the 70w model can out-perform 150w metal halide fixtures.

Color Spectrum

Photosynthesis is vital to almost all corals and plants on the planet, but they do not just need any kind of light, instead they require light in a specific ranges of spectrum in order to survive and thrive, namely the wavelengths that Chlorophyll A and Chlorophyll B require, as illustrated in the diagram to the left, since they are the two most dominant forms of Chlorophyll found in corals and plants.

Enhanced Growth and Coloration The R420R Lighting system is designed to provide all ranges of colour spectrum required by corals and plants to enhance their growth rate, improve their colouration and at the same time giving your aquarium the most aesthetically pleasing combination of colours. Available in a new 15,000k colour temperature and now coming as standard with wide angled nano-tech optics for a greater blend of spectrum. An uprated performance package has been installed in this new model with 6 extra LEDs per lens kit. The R420r will meet the requirements of even the most sophisticated group of marine and reef hobbyists.

The Maxspect R420R LED Module 320w 15000K also utilizes the 410/420nm Super Actinic LED chips, the spectrum that's crucial for the success of any reef and water plant aquariums as it is required by Chlorophyll A for photosynthesis, where absorption peaks at 412nm.


The Maxspect R420R LED Module 320w 15000K is designed to be primarily cooled passively, the body of the R420r is crafted entirely in aluminum, serving as a large heat sink, together with an ingenious aerodynamic design, cool air is channeled through the bottom of the fixture and heat will be dissipated through the aluminum chassis. With a built-in temperature controlled system, active cooling will be engaged as needed to ensure optimized performance.

User Programmable

Photo-period Profile

With 6 Time-Points, users can program their own photo-period for their aquariums, fully control the intensity of light their aquarium will receive from dawn to dusk.


Latest in LED Technology

Utilizing the latest high performance high intensity Cree XLamp® XT-E / XB-D and SemiLEDs, equipped with 120° degrees optics, the R420r will consume less power yet producing more PAR (Photosynthetic Active Radiation) for even your most demanding corals.


The Maxspect R420R LED Module 320w 15000K utilize the latest in LED technology, including Cree XLamp® XT-E / XB-D and SemiLEDs high intensity LED chips distributed in 2 different channels, offering unmatched performance and versatility.
