Of course it would have made far more sense to stay with the 2D principle

With LED lamps it's more likely the PS (dodgy or cooked capacitors etc)
that will fail before the actual lamps.

So unless you have a way of persuading manufacturers to use a *good*
separate power supply, is there much point?
