Yes but there is only ONE bulb that is USCG certified in an aftermarket fixture. A Dr. LED Polarstar 40 in an Aquasignal Series 40 meets the standards and has approvals.
I had a 20W anchor light so for me it was a HUGE savings in Ah. Personally I prefer a complete unit such as those from Hella or Aquasignal as they will likely be more reliable than the Dr. LED bulbs have been.
My old anchor light drew 1.74 amps or 17.4 Ah's over night
My current anchor light draws .11 amps or 1.1 Ah's over the same time period.
That is 94% less consumption!!!
