Testing 2 pin 13 watt preheat PL-L and PL-C lamps

I am testing 4 preheat 2 pin PL lamps. The twin tube ones or single U are known as PL-L's and the quad or twin U ones are known as PL-C's, at least that is the name I know them as. I am doing a 2700K (warm white) Uspar quad, a 4100K (cool white) Philips quad (Philips quad's being my personal favorite,) a 5000K (slightly lower than daylight) GE Biax and a generic Ace branded 7000K (I call them ice cold, there's no official name I know of) single U PL-L lamp all in a screw in PL adapter which is inside the pyramid lamp, showing variations of the colors and each brand's/type's startup blinkage. Afterwards, the 4100K philips quad, my personal favorite, goes back to the pyramid lamp. Comments welcome. Enjoy!

Let Me Re Fraze That, The Philips Quad Can Be Found At Home Depot.

Not the one by where I live, and when it did, was just the warm white ones. And for the Sylvania PL's, all I can say is stay away from those as their tips break very easily.

Phillips are the best PLC bulbs ,they last much longer than other brands !!!!
