I couldn't wait to get a two light 4-foot set. I also have the MT-PROS but these are disappointing. Why? The have to be charged all of the time they loose thier charge way to fast imho. Futher, they are supported by Sidus Link but they are not supported by Sidus Link Go. So, no cool lighting options or designs are available. My 150c's, MT-Pros, & even the bulbs are supported by the program function but not the PT series. I was hoping a firmware update would be released to support the program function but none. If you need a basic tube light, then these will work. But if your wanting to do some complex lighting scenario these aren't the lights. Disappointed with the battery life and lack of program support!
