In Minnesota I think there
is a deal going on with Home Depot and the power company because the 60W
Philips bulbs that are normally $40 online everywhere have been $15 at
Home Depot (here) for months.

They're about $40 at Home Despot. I was there yesterday to check. I
would probably have bought them except that the cheapo 8 watt Ecosmart
LED lights were on sale for $10/ea. I don't know if you caught my
comment, but I have 3 of them (now 4) but only one generates RFI. I
was going to exchange it for another, but forgot to bring it to the
store. Maybe next time.

The best price/performance is at the 60W level where the $15 bulb
produces 810 lumens for 12W with color rendering at something like 80.
The better version of the bulb does 1100 lumens (or so, can't remember
the number exactly) for only 10W and has about a 99 color rendering
rating. And is $50, only available online. I'd love having that one,
but the math doesn't work out even if I have it for 30 years. I'll wait
for the price to go down.

By comparison, the 8 watt EcoSmart 40w bulb produces and insipid 430
lumens and a 3000K color temperature. Like all the blue+yellow=white
bulbs, they tend to favor the yellow. My eyes can be easily fooled,
but my camera and spectroscope shows the obvious:

Argh... I can't find the spectra photo. These look like fun:
