GU10 bulb rated 4.5w. Can I replace with 5w GU10? LED bulbs

The kitchen was completed almost 12 years ago. It had 10
GU10, 4.5w, 6000k, 240v 50Hz bulbs (LED type) One bulb blew last night.
I have swapped over a bulb to ensure the unit/bulb holder is not at fault.

To get the same effect, I'm only really seeing 5w, 240v GU10 bulbs. I

Question is, can I replace it with a 5w LED?

The other problem which I will have to ignore possibly is the design as the present bulbs have grey fins surround, a bit like an aircraft engine fin design, and can see any in any power rating.
The present bulbs are by 'Kinghts' fire-rated, very bulky downlights.

All help will be gratefully received.

 

Great. The consensus is go ahead and if required, go for the 5w as opposed to the existing 4.5w.

The fins, give the lights a distinctive finish but been searching since and will go for a satin steel surround.

The 6000k is also a challenge as most bulbs I have seen are less than that.

I will revisit the thread just in case there is more help/tips here.

PS: I thought I had already posted the above bits but had not. I've been looking for hours and there are loads in white plastic but hardly any in any metal colour, ie satin but a few in chrome but no fins.

NB. As I intially stated the current GU10 bulbs are 4.5w and 6000k. Can I go as high as 6w's?

The fire-rated downlights are not 'knights' but Knightsbridge, appear quiet surdy in the wires inside the ceiling.

 

All posts were noted as very helpful. I'll buy you all a pint if I see you are my local.

 

Cheers to all
Yes, I am trying to match the old bulbs.
We got one Friday/yesterday, no fins etc, same brand, same k's ie 6000k's
The new bulb was 5w as opposed to the existing 4.5w

I have another question as the old bulbs are "50Mz" but the new bulbs, I could not see the 'Mz' on any of the new bulbs in stores.
Does it matter and what is this rating, please?

The 'lumens' or whatever it is called, along with the 6000k that are described as 'daylight' are there different lumens in the 6000k range and how would this impact the light. The old bulb does not state lumens.

In the new bulb, as above, the light is not as white possibly due to the old ones having a flat face and three little yellow squares and the new bulb having small dome glass.

I am researching for another bulb and to match, may change all bulbs at 600k but as you all know, they don't make anything like they used to.

The exisitng bulbs are 240v new one is 230v - My OH felt light was a bit yellow. We are used to the gallery lighting as it is a black-and-white kitchen. I guess you get used to the light

All help will be appreciated.

 

Cheers all.
Tilt, what you said. "
NB their stated 9 watts bulbs, I measured these at 3.8 watts (approx 40w equiv)
And a (proper yellow coloured) their 12 watts measured 4.6 watts. (approx 50w equiv)"

Are you saying that their wattage advertised was wrong? Cheers in advance.

 

Tilt, looking at the link, do you see the yellows or the glas on the GU10 9w, please? I think those are the ones you bought and I'd be looking at 6000/6500k
Cheers.

 

Hello
Thank you.
I'm looking at a couple of others as well and when ordering, I'll decide which to order first and just order the one initially - if it matches, then I'll order the others
I do appreciate the time and effort you have put in trying to help me.

 

@Tilt
looking at the GU10 on the link you provided, they state 15w. Will that be ok for my bulb holder as the current ones are 4.5w as it states o the bulb and I'm not sure it it is per one of those small light units in the bulb or total power? The present bulbs have 4 of those little light units per bulb. Thank you.

Edit. Sorry the bulbs have 3 light squares per bulb and non the wiser if the 4.5w is per bulb or times 3 IE per little unit.
