We got an electrician in to replace 60 wall lights in the office, which are spread across four floors and 5 RCDs (on two different CUs).
They look a little like the enclosed picture (but are not exactly the same). Behind the screen are two E27 fittings and the electrician has put 2 x 70W halogen bulbs in every light.
The problem is that around twice a week we lose a bulb and, when that happens, it takes out its neighbour (in the same light) and trips the RCD.
There is no sticker on the light stating what the maximum wattage is but, to me, 140W for every fitting (there are four in an average sized room) seems overkill.
Before the lights were replaced we didn't have this many failures (previous lamps were single 100W units) - do you think that if I simply replaced every single bulb with a pair of 27W low-energy bulbs, that would slow down the attrition rate and would stop tripping the RCD when we do lose a bulb?
You may suggest I get the electrician in but, TBH, it was his spec in the first place and we've had the lights for around four months now.
Ta in advance
