Great service. Fast (next day) delivery. Great price. The lighting units are more compact than I imagined but are very bright. Adding 4 to a small workshop that had old fashioned tube lighting has turned it into daylight! Being pre-wired meant I installed them (on chains) in less than an hour. Highly recommended.
