Upgrading MR16 TO GU10

[atpm]

Hi all,

I have a failed transformer in a bedroom and want to convert all the bulbs in this bedroom to GU10 (4 bulbs) This is so I can use LED bulbs without hassle.

Is there any type of notification needed for this type of work? Can I just get on with it?

Thanks

It's not the 1st of April yet is it ??

Whats wrong with tamlight??

If there are downlights on the market with both leads out they must be class 2 fittings. How can i state that, because the body of the standard 12v downlight has not been designed for a 240v lampholder simple.

How can you possibly state that? I'm not aware of any photo's and there are downlights on the market with both leads in the packaging.

They may well be fine nowadays but I've been unimpressed in the past.

There were, and still are loads of "open" downlights on the market which can be MR16 or GU10

and , as an aside, the confusion over the purpose of fire rated downlights. they are fire rated not to stop them catching fire, but to preserve the fire barrier (if applicable) into which they are fitted, to prevent the spread of fire ( however caused) through the ceiling.

MR16 is the size of the multifaceted reflector in 8ths of an inch. GU10 is a type of base.

Most GU10 lamps are MR16. Your thread title is meaningless, please explain.

Those downlights are designed for ise with selv (12v) not 240v

How can you say that? His existing lamps are MR16, i.e. multifaceted reflector 16/8ths of an inch in diameter. MR16 lamps come in 12v, 24v, 120v and 240v. MR 16 is NOT a type of base.

Or both at the same time.
MR16 is the size of the lamp, not a base. GU10 is a base not a type of lamp.

In common parlance... GU10 is commonly used to refer to a 240v reflector spotlamp... MR16 is commonly used to refer to a 12v reflector spotlamp.

You've got a lot of convincing to do since nearly every single supplier I've seen uses MR16 to refer to 12v reflectors spots and GU10 to refer to their 240v equivalent.

It's like the term ring main... you say ring final circuit to a customer and you can see their eyes glaze over, but say ring main and most of them know what you're talking about... a bit like MCB, RCD, RCBO vs Fuse. Consumer unit vs. fusebox.

If someone says to me MR16 I immediately think 12v reflector spot with push fit pin style connections... GU10, 240v reflector spot with a bayonet style twist lock connector.

That does not make it right does it? We are professionals on here and should use the correct terms. The suppliers, and others, will never learn if they are not corrected.

Let’s not try and reinvent the wheel, they are 12v MR 16 - 240v lights are GU10 and an American boxcutter is a Stanley knife deal with it ........

George, you were banging on about this before. It's not a problem - life's too short. Bet you hate it when people say they're Hoovering up!

Strictly speaking the MR is more to do with the reflector, the lamp fitting base is actually GU5.3 but they are commonly referred to MR16 which is technically incorrect
