Product Review: JBJ Unibody Dimmable 54 Watt 6500K-20000K LED Fixture

Item Code: JB007721 (Blueberry Blue)

Useful information:
  • Fits up to 5/8" rim
  • Faceplates available in multiple colors
  • Gooseneck mount raises approximately 7" above the rim, and 11" over the aquarium.
  • Feels durable, clamp and gooseneck felt solid, and did not wobble when attached to the aquarium.
  • Acrylic shield built-in protects the optics from moisture and splashes
  • 3W Edison LED's, 6 cool whites, 6 royal blues, and 6 blues.
  • Manual dimmer switch adds flexibility, but can also be controlled by an aquarium controller with its 0-10v two channel ports.
  • Excellent light spread, one unit actually lit up my 36x24x20 aquarium. Sorry, no PAR meter, but I would feel comfortable putting SPS corals in the center area of the light spread. 
Nice quality box with a magnetic open/close flap
Package contents: Unibody LED Fixture, Gooseneck mounting arm, Universal clamp on mount, Duo 700 driver, Fan power adapter. Also included was a 12 month warranty card.
One of a kind - Marine Depot.com logo etched into the blue faceplate - Sexy! 
Top fan, slightly audible, but not too loud. Very similar to a regular computer fan. Using an Android App - Sound Meter, I had a 18dB increase when the fan was plugged in. Unit Dimensions: 8 x 6 x 0.92 inches
18x 3W Edison LEDs, 6 Cool Whites, 6 Royal Blues, 6 Blues and it includes an acrylic splash guard.
Gooseneck clamp mount
Will fit on 5/8", and perhaps 3/4" if the plastic and rubber bumpers removed.
Flexible gooseneck. The length of the gooseneck is perfect for aquariums up to 18 inches wide (front to back). On my 24 inch wide aquarium, if it were mounted on the back, the fixture would need to be pushed closer to the water surface extending and angling slightly for adequate coverage towards the front of the aquarium.
Approximately 12 inches from the back of the clamp to the front of the fixture.
Approximately 7 inches above the rim of the aquarium
Duo 700 2 Channel Driver Box
Manual sliding dimmer switches on the left for the white and blues. Rocker power switch for On-Off-Controller. This fixture can be controlled by aquarium controllers with 0-10v modules.
Driver box can easily be mounted
The unit will require 3 power outlets - One for whites, blues, and fan.

Final Thoughts:

I was pleasantly surprised by the new dimmable light fixture from JBJ. I loved how I was able to manually dim the whites and blues seperately and get the color spectrum I wanted for my aquarium. Plus the optional 0-10v for aquarium controller functionality is definitely an added bonus. The gooseneck mount provides plenty of flexibility while at the same time feeling very solid and secured when attached to the aquarium.

The pictures above were taken with a camera phone and they do not accurately display the colors that were seen in person. The LEDs provided a mesmerizing shimmer that added a whole new experience to the aquarium coming from T5 fluorescent lighting. The coverage that this one unit provided on a 36x24x20 aquarium was fantastic. I do not have a PAR meter, but I would feel comfortable keeping SPS corals in the center area of the fixture.

JBJ has created a great product that looks as good as it functions, I would recommend it!
