Time to look for lights for the new 140

LEDs of course.  At a minimum, we want a fixture with white chips from CREE, a full spectrum of colors, integrated tank mounts (sits on the top rim of the tank). Cost is a concern but this is not a place to skimp.

The tank and stand are about a week away, so it is time to pick a light fixture manufacturer and supplier (if the two are not the same) and model.

Please stay tuned …

For the fixture, we also want a thin, edge-to-edge (for lack of a better term) unit. For a manufacturer we chose to look at  Reef Breeders first.
The next step is choose a model.

Note that like most electronic devices these days, the maker is likely not the builder. The supplier does R&D, design and maybe some final assembly, and outsources the components and build.

MACNA 2016, lighting

LEDs continue to be the theme.  The improvements this year appear to be not in photons, but in the array of mounting options, especially on the tank.

Many reef keepers struggle to mount or hang lights in a way that doesn’t detract from the overall look of the tank.  Help is now on the way in many forms.


Cree does it again!

Cree, Inc. raises the performance bar again with the demonstration of the first 200 lumen-per-watt (LPW) LED concept luminaire, which is more than twice the efficiency of the
best linear fluorescent luminaires.

Full Spectrum LEDs

In addition to being helpful and responsive, the folks over at LEDGroupBuy have made the extra effort to offer a number of items that some might consider nuanced, but to others important.

Like a range of violet LEDs for example, 390 – 430 nm.  For many, the 430 might be enough for their full or fuller spectrum lights.


As we wrap-up 2012, more questions than answers, but that’s reef keeping. 🙂

Royal blues and whites, or full spectrum?  What is full spectrum?

DIY or off-the-shelf fixtures?

Asian imports, no-name, or name brands?

Spread and coverage vs. PAR, lenses, and shadowing?

CREE or Luxeon, or does it even matter?
