This is part of the clearance sale that was mentioned here, but that post did not mention the most attractive bulb there, a 20W 2000 lumen 4000K one.
Here's a photo of the specs on the box.
This is the manufacturer; it looks like that series of bulbs was their attempt at breaking into the consumer market which they've now abandoned.
They have a C-Tick so they shouldn't cause interference (e.g. with your TV).
There were maybe 30 left when I was there. If you buy "a box" you can get them for $1 each, but I'm not sure what constitutes a box!
What a beast!
