Hello WLL, Originally I went on line to research domestic led lighting. Liked what I found, and then searched for suppliers (I live near Leicester). Your company name suggested you knew a thing or two about such lights! So I researched you too; and still looking good! I immediately headed to your w/ho. in Leicester. Where your staff member "Jess" very patiently handled my ignorance and my endless questions; with a detailed technical explanation, what they are best used for, and demonstrations of the lights in use. Now I know A LOT about LED's!! All done very pleasantly and with great humour by Jess. And I duly bought some bulbs; they are brilliant!
