Cheap and good – 3V~8.4V 5W Cree 3-Mode Circuit Board for Flashlights (16.7mm*5.6mm) Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

Pros:
This driver fits pefectly in a p60 drop-in, although you should put some insulator on the top so that the Led+ and Led- don't short.
The current is about 1A on high.
The high mode is just as expected, and on low flickering is not noticeable.
Cons:
Low is much lower than stated, about 100mA or even less (just an estimation - didn't check it with a multimeter).
Strobe is almost unuseful; it would be much better if the three modes were high - mid (35%) - low (10%).
The wires are very thin and could have more insulation.
On a single fresh li-ion battery it draws only 0.68A on high, meaning that the regulation doesn't work at less 4.5V.
Other:
Bottomline:
A good led driver for a great price, really current regulated (but only with at least 4.5V).
