Yes. Used one of the companies that BGE had on their recommended list as they handled the paperwork and provided me credit for the rebate immediately. I did compare the quote to another electrical installer not associated with BGE and it was very fair so I went with the BGE name. I could have done myself as the wiring is straightforward but did not want to learn how to use a cherry picker due to the heights involved, and installation added cost was small.
Look closely at the warmth scale (warm vs daylight vs bright), guaranteed length of life (usually 10,000 hours or more) , wattage equivalence (went from 500w used per bulb to 35w), and light spread (flood vs spot) as those are the variables involved. Check brand quality feedback online as some of the Chinese knockoffs are poorly made.
