In So. NJ, some of the LED lights were clearly marked as receiving a NJ state subsidy. I say "were" because I didn't see an explicit sign re-stating that today, but I'm unsure the prices have changed: they may have just dropped the notice. Anyway, any subsidies will vary from state to state.
I don't recall seeing this particular bulb, however.
I've replaced the majority of my bulbs with LEDs and won't buy further CFL or incandescent ones except where unavoidable. It remains unclear how durable they will be in winter [sub-zero] outdoor fixtures, BTW.
