Again based on the GKV 600W lamp the PR-3040 is capable of giving almost as much light as a traditional 1000W par 64 parcan. The housing is elegantly designed for easy installation and operation. The Pro Par is supplied as standard with four lenses that can be easily substituted to provide various beam widths and shapes. Note, the PR-3040 is designed for and should only be used with the GKV 600W lamp
