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.
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.
A good led driver for a great price, really current regulated (but only with at least 4.5V).
