Bolting Lamp to Concrete

I am wondering what the most effective way of bolting down an outdoor lamp (5-6' high; not too heavy) to a flat slab of concrete in the ground. The lamp comes with little bolts but I'm thinking I need something to maybe go completely through the concrete.

And, I'm stupid enough to need details on drilling a hole in concrete, type of bolt I should get, etc.

Thanks to all.

I would use either a wedge anchor or a sleeve anchor

drilling a hole will take either a hammer drill with the proper size masonry bit or a star chisel of the proper size and hammer.

You will not need to drill through the concrete.

for a nice touch, once you get the anchors tight, you can remove the nuts used to tighten them, cut the studs down and use an acorn nut for a nice finished touch.
