I was really pleased with the light fittings, although I can't comment on longevity as they've only been installed a week, the light output was great, colour temperature consistent throughout the batch, and they dimmed beautifully with zero flicker and went down to a nice low level. My only gripe is that there is no scope for trade accounts. I think the products are fantastic, but unfortunately as an installer I will probably look elsewhere first for most of my projects as I need to make a margin in order to offer a guarantee and maintain a healthy business, and if my clients can buy direct for the same price I can buy for it makes me look like a charlatan when I add my markup.
