There are a lot of different paver style lights on the market. I would never install any of them myself. Forget about the horrible effect they produce (alien landing strip effect) and just look at the fixture build quality. None of them are designed to stand the test of time. They break, crack, seals fail, sockets and connections fail, lenses yellow, etc.
I would be guiding the client away from this completely. If there is no budget to do the job well / right, then there is no point in doing it poorly. Do you really want your name associated with a poor performing and visually distracting job?
Short term pain for long term pain... its a loose loose proposition.
