JBJ Macro-Glo Adjustable Refugium Light

  • Adjustable Clamp on Fixture (Similar to C-Breeze)
  • Integrated Ballast inside lamp, no ballast to replace
  • 15 Watt lamp
The energy efficient MACRO-GLO refugium light is the smart solution for sumps that require powerful light output in a space-saving form. The MACRO-GLO securely clamps to the rim of the sump and can be easily positioned out of the way for routine maintenance without the fear of dropping the fixture in the water.

These unique lamps equal 5 times the brightness of traditional incandescent lamps while producing less heat and lasting an amazing 8000 hours. Each lamp has integrated ballast and fits the standard medium based lamp socket. Lamps will be the only item that needs to be replaced!

The MACRO-GLO is offered in 15 & 25 watt versions. They are installed with a 6400K Daylight to promote macro algae in refugium environments. All models include a parabolic reflector to maximize light intensity and coverage.

The MACRO-GLO can be adjusted at the head, arm, and base to fit your desired application. The unique articulation allows endless configurations for virtually any refugium. The clamp includes a spacer and allows for 360 degrees rotation.

Came broken

Pros: came broken, cant tell.

Cons: poorly constructed.

I received my light a day early but it came broken. The bulb and electrical wires are falling out of the base. Looks like bad craftsmanship, or should I say, bad chinese manufacturing. Would not recommend

Average at best!

I have owned this fuge light for over a year now on my sump and it will not grow my Cheato Marco algae for some reason and I have the 25watt fixture. Also, it only will only clamp down on a rimless sumps. Very expensive for not very well build light for your fuge.

Nice light for a sump refugium system. Compact and clamps onto the sump aquarium around drains and return lines.

Good light, doesn't fit

This light's clamp does not fit on the rim of my sump. I didn't feel like the return hassle so I super glued the parts of the clamp on to the rim and so far has worked fine.

I have had the unit in operation for 4 days and the bulb has already gone out. Since the bulb is roughly a third of the price of the fixture I would say definitely NOT worth the money. I am looking for a new HOB refugium fixture.

refugium light

Very happy with this 25 watt light. It does the job...I was a little nervous about the clamp. My sump is 1/2" acrylic and wasen't sure if it would fit... well no problem, it fits great, and is very secure. Yes I would recommend the light !

Macro-Glo Light

I have this light attached to my DIY Refugium that has a large amount of Chaeto growing and is teaming with pods. The rock has a lot of color since I added this light. It is easy to use, the mount could have been a little better but it works. The only complaint I have is there is no splash guard for the bulb. Meaning if you have bubbles in popping under the light the water will reach the light and leave salt creep on the bulb. Otherwise it is a great light for the price. I would recommend this light.

Failed Out of the box

The product failed within 2 days of use. It had an electrical short that nearly fried my aquarium controller and caused an electrical surge that shut my entire tank down. Would not turn back on after this and I returned it. Typical JBJ cheap, poorly made junk!
