I bought 3 sets of these lights for my outdoor landscaping at $40 each set. After 2 days, all of them began reverting to strobe on their own at different times. Even though they were set to steady "white" light, one by one they all started flashing and choosing whatever color or rhythm they wanted. I cant get them to stop. I have 3 remotes (1 with each package) but once they are strobe-ing, none of the remotes will shut them off! You  have to remove at least 2 of the 3 batteries in each light to get it to stop!!!! I changed to an even higher grade battery, and still did same thing. I have spent $30 in batteries alone and I have useless lights. Do not buy these!!
