Great upgrade for an older model.

Purchased the KX4D to replace a P60 XC2 bulb. Much brighter light and greater battery life now. Only issue is I have to unscrew the battery cap 1.5 turns to prevent the light from automatically coming on and then crew it in when I want to use the flashlight.

Illumination vs battery life

Battery life using this accessory is longer; however, the brightness level of the light emitted seems less than adequate for many emergency situations.

LED Conversion Head with Crenellated Strike Bezel

This LED Conversion Head with Crenellated Strike Bezel is sort of expensive when compared to the cost of the unit it fit on. However, once you see what the light out put is you won't care about the price. AS it is just that amazing.

Perfect fit

I bought the KX4D to upgrade from a previous version. The fit was excelent and the cuality is exceptional. The light beam is not as directional as I was hoping for but in low light conditions it gets the job done. No complaints
