Optilumen RKS Universal Fluorescent Fixture Retrofit Kit. Easily converts most all your existing residential and commercial 4 and 8 foot T5, T8 and T12 linear fluorescent light fixtures into an integrated LED light fixture. This retrofit kit works with the earliest to the latest versions of ceiling mount, four-foot and eight foot fluorescent light fixtures, regardless of the style, manufacturer or existing ballast type including linear high-bay, strip or wrap fixtures and even chain suspended shop lights. Since the retrofit kit contains the LED driver, there is no guess work to determine if it is compatible with your existing fixtures’ magnetic or electronic ballast. Super simple installation in 3 easy steps: 1). Remove existing bulbs and ballast. 2). Attach magnetically backed driver and connect to AC power source. 3). Attach magnetically-backed LED strips and quick connect to Y-harness. If your fixture isn't steel, no worries, the kit is pre-drilled and comes with mounting screws. The fixture is DLC listed to qualify for commercial lighting rebates and special incentives in certain regional areas.- One retrofit kit converts a 4 ft. fixture with 4 lamps or two 8 ft. fixtures with 2 lamps; See our Optilumen RKS Selection and Savings Chart

Nice material, stitching. Fit was unorthodox.
Size: Small, Color: Light Grey (Stretch Fabric)
putting on the suit for the first time, pants first, I thought that I had gotten a steal of a deal! The fabric was of good quality, had a good amount of stretch and was just long enough for my long legs. (typically wear a 32/34, but cuff the jeans once). It was the top section that I had an issue with. The shape of the shoulder-to-neck area was very pointed. As someone that has almost no trap muscle, this meant extra fabric that sagged on the my shoulders and gave me an unkempt look and I'm not sure this is something that a tailor can fix easily. If you have a little more beef up top, this would probably work for you. I wish it would have fit differently because I was impressed by the quality.

Do not waste your time
Size: 3X-Large, Color: Black
Wow! Lol extremely disappointed. I ordered this suit based off of the size chart and my accurate measurements. It was EXTREMELY small. So small that I could barely get my forearm through one sleeve. Not even close to my measurements. And to top it off, it was delivered in a clear bag, exposing the contents to the carrier and possible package thieves. So unprofessional.

Affordable, Stylish, and Fast Shipping!
Size: X-Small, Color: Black
I was hesitant to order this suit for my son’s homecoming, but wow! The quality is outstanding, it fit perfectly with no alterations, and honestly looked better than an overpriced fitted suit. He received tons of compliments, and I’ll be ordering more soon. Plus, it arrived the very next day. Highly recommend!
