Yes, and you are welcome to borrow it. PM to arrange a meeting time.
I happened to have two Cree LED bulbs marked 2700K 800 Lumens 9.5W 120V 60 Hz 79 mA on hand. From my household 120V, both draw about 8 Watt, 70 mA, and both measure PF = 0.88 using my Kil-A-Watt.
Their markings indicate ~unity power factor: 9.5W / (120V x 79mA). Small print also says they are UL Listed and suitable for damp locations. Another marking 2213 suggests they were manufactured in Week 22 (late May/early June) of 2013.
What brand are your LED bulbs?

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
