Replaced 10 5ft florescent fittings with 9 LED equivalent white light in a building we use as a workshop, I think I have achieved a satisfactory finish on timber and when loading the van I find things I did not see, the lights are light in weight and easy to fit they do not blind me if I look up they are an improvement but wonder if I could of improved things more, I may add a LED flood light over the bench. The service was good and I would use this company again I have left the review late to see how the lights performed and to date no problems
