single ended bulbs vs. double ended bulbs

[fkshiu]

SE pros:
-higher PAR output (because no tempered glass shield is required)
-slightly greatly light spread
-easier to install than DE

DE pros:
-compact size
-easier to clean salt spray off of (because of the tempered glass shield)

It used to be that there was a greater variety of SE bulbs, but that's no longer true although many DE guys still long for the day that Radium comes out with a DE bulb.
