I just hope that being a skeptical curmudgeon myself doesn't turn you off to something that (I guess) is good for certain applications.
But "10 Watts, or maybe 5 Watts" and NO mention of lumens suggests that they didn't want to advertise it as a "pitifully dim little light".
I would think that a "clip lamp" could be as inexpensive or cheaper, and then you could pick any CFL bulb including bright ones.
Sometimes they hint at the brightness (Lumens) from a CFL by citing the wattage an incandescent bulb WOULD need to be AS bright as that CFL.
Like a CFL may say "60 Watt equivalent" because it puts out as many Lumens as a 60 Watt incandescent (870 Lumens) but the CFL actually only uses 13 watts of electricity to create that many Lumens.
A "100 W equivalent" CFL only uses 23 W of electricity but produces 1600 Lumens.
