Our take on the 2:1 White & Blue ReefBar LED Light Bar 12000K + 453nm Actinic 2ft

The ReefBar is a slim, fanless 2ft LED strip for reef and freshwater tanks, mixing 12000K white and 453nm actinic blue in a 2:1 pattern so one bar gives both. It runs about 9 watts and 650 lumens per foot from Epistar LEDs, is fully dimmable with a separate wireless dimmer, and links end to end up to 16 feet on one power supply. Output is modest per bar, so it works best as part of a multi-bar setup rather than a single fixture over a deep tank. Buyers call it bright for its size, well built and easy to fit, though the dimmer is an extra and the bars need stacking to reach reef-level PAR.

What reviewers say

Buyers describe the ReefBar as very bright for its size, well made and true to the listing. The dimmer and remote get frequent praise. Complaints center on needing more than one bar for deeper tanks and on the dimmer being a separate purchase.

About the 2:1 White & Blue ReefBar LED Light Bar 12000K + 453nm Actinic 2ft

The ReefBar is an LED light bar for reef and freshwater aquariums. This 2 ft version has a 2:1 color mix: the LEDs alternate 12000K white, 12000K white, 453nm actinic blue, so one bar provides both white and actinic light.

The housing is extruded aluminum and is completely waterproof, which keeps out salt creep, splashes and bubbles. The bar is slim, at 3/4 inch wide and 3/8 inch thick, and runs silently with no fans. It uses high-lumen Epistar LEDs with a 140+ degree beam for even coverage across the tank.

Bars link end to end, with power in on one end and power out on the other, for up to 16 total feet on one power supply and dimmer. The light is fully and smoothly dimmable with a wireless dimmer, which is sold separately. More than 10 ft of cord runs from the wall plug to the bar. A single bar adds up to 30 PAR at the bottom of 24 inches of water with the light 2 inches above the surface, and up to 25 PAR when mounted 6 inches up in a canopy.

Questions and answers

Is one bar enough for a reef tank?
Usually not. A single bar gives roughly 30 PAR at 24 inches of water. Reef tanks typically want 90-120 PAR at the sand, which takes about three bars at 18 inches.
Does it come with a dimmer?
No. The wireless dimmer is a separate item. The bar itself is fully dimmable once you add it.
Can I connect several bars together?
Yes. Bars link end to end, with power in on one end and out the other, up to 16 feet total on one power supply and dimmer.
Is it safe near saltwater?
The bar is fully waterproof, so splashes, salt creep and bubbles stay out. It is also fanless and silent.
What colors does the 2:1 bar produce?
It mixes 12000K white and 453nm actinic blue, with LEDs alternating two white to one blue, so you get both in a single bar.
Will it fit under a hood?
At 3/4 inch wide and 3/8 inch thick it fits most hoods. Mounted 6 inches up in a canopy, a single bar gives up to about 25 PAR.
