Hi, just thought I would add to this...
My CND UV lamp is 14 months old but still has 71 hours of lamp life left. While a clients hand was in the machine two days ago my lamp crackled and the left side lamp went out. I decided to carry on to complete my clients Shellac manicure but when I put the machine on for another two minutes the upper left lamp went out in the same way. I purchased a whole new set of lamps (over £40) from Ellisons, Birmingham and they came the next day. When I put the lamps in the two on the left would not light up - the problem is with the connectors (as everyone on here seems to be saying). I Collected loads of evidence from Salon Geek and rang my supplier. They of course talked about warranty - mine is out of warranty, but as I said, its not a warranty issue as these lamps obviously have a design fault - some people are even saying that they have had the machine tested and found out what the fault is (resistors, someone said). The customer service were very friendly and the lady checked with a colleague and straight away said I could have a new machine FOC. I also asked her to take back the lamps I had received as I now did not need them. She has arranged for the machine and lamps to be collected. Obviously I will be keeping everything crossed that the same does not happen again. I thought I was going to have to call trading standards...... not this time.
