+1 for splitting the system. Then you know the backup is working too.
Agree, you don't want one unit to be able to close a store like that, especially if its longevity is suspect to start with.
If you got two of the 300W units, then each would only be running at 50% capacity, helping longevity, and in the event one fails the other could handle 100% of the lighting load until a replacement is secured.
If you wanted to get fancy you could wire a pair of transfer switches so that if either PS failed the 140W it was handling would automatically be sent to the other PS.
