We had not dealt with "International LED's" before, but a booklet landed on my desk at work ( source unknown ! ) which had details of L.E.D. ceiling panels. We had been thinking of replacing the current fluorescent tube fittings with L.E.D's for a while but, as it is relatively new-ish tech' had been reluctant to replace all the panels throughout the entire site. We asked to be supplied with just one panel for trial purposes; "No problem" we were told and, sure enough a single panel arrived incredibly quickly, well packaged and at reasonable cost. Assuming the trial goes well we will return to "International" for the substantial number of panels required. The panel is doing fine so far.
