Ronv: while that might work, I wouldn't go jumping to conclusions. The O.P. said they wanted a "transformer less power supply": that doesn't necessarily mean they want to connect the LEDs directly to the power line, since they did say "power supply".
So let me ask you, the O.P. (original poster): what exactly do you mean by that? Do you want a power supply that doesn't use a transformer (like a switch-mode power supply, although most of these do use transformers)? Do you want to plug this directly into the wall socket without any kind of power supply? Something else?
