Over the past few years Efficient Lighting has been my online supplier for spare tubes for my Green Brook under cupboard lights. I recently ordered 2X20 watt tubes which, on arrival, were the incorrect size. Having then looked on other websites I concluded that my particular fittings had been discontinued & presumably the alternative was a different size. At that point in time I had the misfortune to have a telephone conversation with Mr Giles Boardman who I believe is the MD. He seemed incapable of grasping the situation & was extremely rude & arrogant. I will certainly not be recommending his company. Judging from other websites I'm not the only person who has fallen foul of Mr Boardman.
