Is it just me, or does this completely fail to mention the amount of lumens it produces, the wattage of the lamp, or the incandescent-equivalent rating? Basically, all the fundamental parameters you'd normally expect when buying a lamp aren't there.

"Eight LEDs provide 587lx of warm, white light for 37 years"

But that's the only reference on the page.

Yeah, which is pretty meaningless because lux is a measure of light intensity at one particular spot and it doesn't provide any information about the distance at which that's measured, how big an area it'll reach that lux value over, or anything. My little 1 watt torch could probably produce ridiculous amounts of lux so long as it was only over an area the size of a postage stamp, for example.
