This drilling screwdriver is the "hammer". I use the model for several years and have been able to test it in various applications. With two batteries, he is always ready for use and screwed and drilled like crazy. For a handset with good torque. When screwing in the power never a problem When drilling in walls only with stone and concrete (What a surprise; o))
With the built-in battery grip, the device fits in any situation well in hand and no battery disturb you when working!
I miss only one thing and that is a bit holder on the device, or magnetic disk. I have the screwdriver still several times and bought later given away.
For lamp I can not say much. Makes a bright light and has a form adapted to the battery.
