There is a three part vertical mounting, a plastic stake, and a metal pole, one half is pass-thru for the wire, and the second is the lamp base. The bulb goes into this part. On the top is a protective plastic lens (that greenish thing in my pictures is plastic - NOT glass) and plastic housing. Overall, these will be fine if there's no interaction with them after installation. However, if they're installed, say, in the northeast where there's snow, and a shovel hits one of these, you can expect it to snap off and be trash. If they're off the beaten path, or edging a yard, they'll likely be OK. Overall, the quality is acceptable, but they're not heavy duty by any walk of the imagination. Decent value for the cost, and they look nice and throw off a nice light (as expected, limited throw, perfect for the purpose). Standard wired install, you need a transformer that isn't included (any 12V will do, as long as you can put out 16w for 4 of them - V=IR).
