I’ve read most of the ‘minimalist’ thread and really appreciate your thoughts on it. I also looked at your blog.
I’m looking for a spotlight / pendant for my 20″ cube. I am keeping a crocea clam / encrusting montis (all in the top 1/3), ricordea, and zoas. I’d like something really modern, that doesn’t ‘bleed’ too much light into the rest of the room.
I’m keeping all my corals in about the middle 1/2 of the aquarium, so it really only needs to cover about at 13″ by 13″ space that is 20″ deep.
I currently use a 250W Lumen Max hanging pendant, but it is so blinding my neighbors even wondered what was going on.
I’d really appreciate your thoughts on this.
Thanks for the kind words. Cube’s present a great opportunity to aquascape, but can be tricky to light properly. 20in makes it too narrow for T5’s to be used well, and the 20in depth means you need some punch. That said, 250’s are a bit too much, particularly given the 13″x 13″ area you wish to illuminate.
Currently there are no true spot lights available in the U.S. Although, that may change in the future, we are limited to the “traditional” lighting sources.
Given the space restrictions and height of your tank Metal Halide is the obvious choice. A 150w DE Metal Halide should work nicely. They are compact which allows a smaller, tighter reflector which can create a spot light effect.
Starting with the pre-made units available, Coralife has a 150 MH pendant that is simple, clean and worth looking into. They are not very popular, but are one of the best looking DE Halide pendants available.
If you really want something that is modern and fits in, DIY is the route you’ll have to go. You often read on the boards people calling certain reflectors poor because they create hot spots and have poor spread. Think the opposite in this case.
Yes, a better reflector can be made, but given your needs the well known “cheapie” DE MH reflector should work well, and focus the light where you want it. A DE retro, like the one shown below can be had for around $150.
Now comes the important part–the exterior. I would suggest a simple “floating” canopy with a minimum height of 5in. This will help prevent light spill. Another option to consider are Barn Doors.
The actual length and width dimensions are up to you. 20″x 20″ will give it a canopy feel, with tighter dimensions creating a pendant feel. Be sure to add vents and a fan for cooling.
This can be made from scratch, or if you go to a store such as Hobby Lobby you can find small pre-made wooden boxes for a few dollars. These work well as the base, then skin as you see fit. For a high-gloss-resin effect look into automotive paint.
These floating canopies can look great hung from the ceiling or wall mounted. Which menthod, completely depends on the room it’s in and your needs.
We hope this helps. Thanks again for the message and we wish you luck in your modern-luminaire-endeavor. If you, or any other readers have questions please post them in the comments section below.
