I just upgraded to a 6ft Orbit Marine Pro on my 125G so these lights are for sale. The 48 inch (legs extend to 60 inches) is SOLD and the 36 inch (legs extend to 48 inches) is SOLD. Or best offer.
History is I bought the 4ft light new in October 2014. The 3ft light was purchased used from a member in October 2015. They stated they bought it 10 months previously but had only used it half that time.
NOTES: Both have some rust on one of the legs where it was over an exposed area of the tank. One of the controllers/clocks ran faster than the other so had to keep syncing the time every week or two. If you only buy one, it's not as noticeable. One of the remotes wasn't used at all. Otherwise, works great, blues and programmability are especially awesome.
Trades I'd be interested in would be low maintenance corals, RC car/truck related or drones (indoor or outdoor/racing/FPV). PM me with pics of what you have. Doesn't hurt to look or ask.
