  • Patent number: 5964524
    Abstract: The invention is a worklight and stand having a multi-legged support and a main pole consisting of three segments. The leg support increases the stand's overall resistance to tipping as well as increases the stand's load resistance. The worklight is adjustable, allowing for the aiming of light in multiple directions. The ability to break the main pole into three segments allows for the storage or packaging of the stand within a container of smaller dimension than necessary for a stand of only two segments.
