I picked these two lights up today for backup lights. They look like black boxes with reefbreeder stickers on them. Approximately 5 years old. Both fully functional. Worth the $30 a piece i paid for them?
I believe those were their basic fixture that sold for something just over $100 to $150 when new. If they work OK and aren't rusty, $30 each is an OK price IMHO. You could get fairly close to the same fixture brand new from Mars Aqua for around $100 each.
