Reef-Spec Light Output For Optimal Coral Growth & Coloration

Over the past few years, Red Sea has dedicated a lot of time to testing and researching LED lighting, and the culmination of those efforts resulted in the ReefLED 90. Designed for optimal growth, while producing great coloration with a pleasant shimmer effect. Red Sea didn't stop with great function and form. They integrated the control of the light into the ReefBeat smart aquarium app and the built-in WiFi lets you directly connect the light to your smart device to set the daily schedule, color, intensity, and other features.

  • Optimal Output For Maximum Color & Growth
  • Perfectly Blended Light with a Slight Shimmer
  • Reef Safe Dual Channel Control with Moonlighting
  • Easy to Control With ReefBeat App


Maximum Spread - 24" X 24"


LED Information:

The ReefLEDs use an ingenious recessed LED cluster that eliminates glare from normal viewing angles. This focuses light into the tank, while the specialized lens provides a homogenous light mixture that blends nicely in your aquarium. The Dual Channel settings let you customize the lighting for your viewing preferences while ensuring the overall spectrum is acceptable to corals and other animals that depend on it for their energy. 

Total LED Power - 90 Watts

Reef Spec Blue - 80 Watts

8000K White - 10 Watts

Moon Lights - 3 Watts

Product Questions

Can these lights be daisy chained together or would 4 lights require 4 power outlets?
Question by: Joe Schlimm on Sep 21, 2022, 11:58 AM
Hey there,
Thank you for reaching out to us. They each require their own power outlet.

Please let me know if you need anything further and take care!

How much space do I need to mount the bracket/light to the back of the aquarium? Currently, I only have 2 1/2" of space between the wall and the back of the existing aquarium.
Question by: Pamela LaBrasca on Mar 9, 2020, 5:02 PM
Hey there,

It will extend nearly 2" from the back of the glass. Should fit if you have 2.5".

Take care

Is there a fixture for these lights that will fits on rimmed tank like a 40 breeder?
Question by: Zhan on Dec 6, 2019, 8:50 AM
Hey there!

Unfortunately there are no hanging kits for this light that will work with a rimmed tank, only rimless.

Hello I was wondering how many of these would be recommended for a 75 gallon tank
Question by: Cameron on Nov 3, 2019, 12:29 PM
Hey there-

For a 75g system we would recommend at least 2 which would provide sufficient coverage for a mixed reef tank. In higher demand systems or systems where large colonies create more pockets of shade you may want to add 1-2 additional LEDs down the road to ensure even PUR distribution and intensity.

Happy reefing! c:

Will these new Redsea lights fit the mounts that came with the all-in-one Redsea tanks? Specifically the MaxE-170 that came with the AI light.
Question by: Matthew on Oct 22, 2019, 4:13 PM
Hey there!

That mount is for AI primes only and will not work with the Red Sea lights.

Take care

What is the warranty on these? I’ll need several for two tanks and don’t want to spend that kind of money for a light that only lasts a year.
Question by: Simon Robert on Sep 3, 2019, 3:10 PM
Hey there,
Thank you for reaching out to us. The warranty is 1 year, however, the light should last well past that with proper care!

Please let us know if you need anything further and take care!
