Totally confused about these but

Can I use a gu10 240v 50w (which I have a number of) to replace a 7w,100-250v

The annoying is I replace this same bulb last yr and they are supposed to last 30,000 hrs)
It's the same fitting I've put it in but will this be a problem for me later on.
I know this must have something to do with low wattage but not sure what.
Can anyone explain, I don't want to cause an electrical problem.
Thank you

From my experience of GU 10 bulbs, the older, halogen ones used to last quite a short time and I’ve been replacing them with the newer LED types which are supposed to last a very long time. But from your post, it looks like you have LED (7 w one) which has not lasted. Might just have been a dud one. It should be ok to replace with the 50 w one anyway.

Reported. Not even the faintest connection with the subject of the thread, just flagrant spamming.

Check your fitting. A fault in one of ours resulted in the bulb lasting considerably less than the advertised 30,000 hrs.

Like Farmor15 I also have been replacing mine with LEDS. I will save money and they last a long time. They are expensive but should pay their way.

I also use LED's and they seem to be lasting well.

Is there a Dummies' guide to light bulbs? I'm baffled by the number of different ones in my house.
