Adam Hall 87463 ultra 19"/1U

A well built rack light with 3 levels of illumination. I have this at the top of an 18U rack and it can happily illuminate all the units from top to bottom. The level memory feature is useful. The goosenecks are sturdy enough and tuck away well when not in use.

A front panel on/off switch might have been useful, but given the price one shouldn't grumble. I could of course have paid a little more and had both the switch and fully dimmable lighting, but this unit does the job just fine.
