I have one ADA Solar I Pendent for sale with two ADA NA Lamp MH-150W bulbs (about 3,000 hours on each bulb). Each bulb probly has about 6 months left of quality life left....so you should be good for a year before you have to replace with a new one.
I am asking $400 for the pendent and 2 bulbs. I am not sure of shipping but we can work that out after the sale.
