I agree Google and get as much information on black boxes as you can before you pull the trigger. However also know that most of the poor reviews online or from people that do not own black boxes. I've heard they will grow algae, brown out your corals, and even set your house on fire. Lol. The support you get after buying one depends on the vendor. For example the group buy vendor on Facebook provides a solid 1-year warranty no questions asked.
One of the main issues with these lights is that they are a entry level inexpensive light. That means most people who buy them are inexperienced reefers. They often fail because they are inexperienced reefers not because of the light yet we all know who gets blamed, that's right the lights. I have been running mine for 16 months, tweaking the diode layout and gotten to the point where I have better growth than I did with metal halide/t5.
And as far as what support is actually needed, the lights are completely modular. Every piece inside have quick clips and it's easy and cheap to replace buy any. If you can get a new driver for under 20 bucks shipped and swap it out yourself in 5 minutes, again what support is really needed?
They are extremely easy to modify if you want to tinker and change spectrum, or even modify for 0-10v analog control through a Reef keeper or apex controller.
Although it's true you get what you pay for, often you pay for more than what you get. For example the group by has sold over 1300 lights, and only had 6 failures. All 6 were easily fixed with a replacement driver or control board, something the end-user was able to do in minutes. Even Ecotec doesn't have that good of a record.
