And - I haven't dealt with too many people who really enjoyed their LED lighting past that fact that they now had an inferior light source that used so little energy to make them feel better about the crappy light output.
That said a metal halide lamp is more difficult to break, about equal in life, better color rendering and IMO is a decent compromise for lumen to watt comparision. :grin: If they made them in lower wattages and developed an instant start and some dimming capabilities they would be easier to sell than CFL...
