L0D(-CE) on 10440 Li-Ion - Maybe there should be a big fat WARNING about this?

L0D are rated 3.3V; 10440 are 4.2V off the charger.
10440s are rated 300 mAh, max safe discharge rate 600mA; discharge rate for L0D/10440 is 1200mA.
I would suggest running an L0D only with AAAs until you are more familiar with the dangers of lithium batteries and how to take care of them.
If you want a small very bright light look at the AA lights.
For example I am carrying a
Ultrafire C3 Cree Q5 5-Mode with 14500.
Light is rated 1.5V~4.2V within the limits of 4.2V of a freshly charged 14500.
14500s are rated 700mAh, max discharge 1400 mA; 1200mA is still in safe area.
This light is slighter brighter than my L0D CE both AA vs AAA and 14500 vs 10440.
The modes are medium, low, high, strobe, SOS - sound familiar?
There are many other lights of better build quality that is equal or lower in price than a L0D.
