Just check jameco.com and all their lower power white LEDs are in the 20...30mA range, lowering tht current only result in VERY dim light.
Only indicator LED (for control panels) require less than 20mA power, and they are REALLY dim. Most efficient brightness/power ratio LEDs are in the 1W...10W range, and these would empty the CR2032 in less than 1 hour !
Another possible advantage of using AAA battery instead of CR2032: you can try to use rechargeable NiMh instead of alkaline (if the 1.2V instead of 1.5V is sufficient, have to check for that).
[Bear 100] Sorry, but LED aren't magic, they need SOME power to produce any reasonable amount of light. And lithium batteries like the CR2032 are among the most toxic waste...

I guess Geckocovers was going for size when they chose the CR2032. If the lifetime for the CR2032 is going to be that short, I would prefer one AAA instead (assuming rechargables work). Having said that, I probably still get the Luxe, but will need to think whether I should get a separate booklight, especially when the light on the Lighted Luxe is on the back of the case when stowed.
