We installed two sets of suspended lights in the kitchen back in 2014. It was one of those things that we installed with every intention of “tweaking” at a later date. However, we never seemed to get around to it! On a couple of occasions we thought it could have been a little bit brighter in the kitchen.
I thought it would just be a case of changing over the light bulbs.
Screwfix stock some slightly brighter 12V LED MR16 bulbs. I thought it would just be a case of swapping the bulbs over. Simples. But no. That didn’t work. Well, it worked for one. But once all the bulbs were replaced, they all went very dim. Some of the new ones stopped working altogether!
Although the difference in the LED bulbs (4W for the old ones and 6W for the new ones) was minimal, it seem enough to tip the old LED drivers over the edge! A quick test with a volt meter showed that the LED drivers where outputting about 4-5V rather than 12V. I later wondered whether it was the defective LED drivers that was producing the dim lighting. However, by this point I had swapped all the bulbs over! I wasn’t going back!
On reflection, the old drivers were 7 years old so they hadn’t done too badly. The replacements were only £15 each on Amazon. Simply changing the drivers over fixed the issue of dim or non-working bulbs.
