A hook clamp has surfaces allowing the clamp to be placed on a support and clamped thereto. The surfaces are such that the clamp can be placed on the support and its weight held by the support prior to tightening. The clamp has a built-in connector for supplying power to the lamp. The clamp has one or more fail-safe holes for securing the clamp to the support with a safety cable. The clamp also has one or more flanges that can be received by a separate mounting bracket, for mounting the clamp and any attached element during storage, staging, or when otherwise not being used.
