12v For Kitchen or CFL

[lisach]

Can anyone explain why I am not being advised to get CFL's given all their benefits?

I like this kind of thing have followed advice on here.

However in speaking TLC and others they advise this for a kitchen x 12.

Very confused and desperate as they are being fitted on Monday...

Do the 12v MR16 use less power than the same number of GU10.

Hopelessly lost Lisa

MR16 and GU10s use the same power for a given wattage.

CFLs use significantly less.

People designing kitchens / bathrooms will always recommend halogen downlighters. They are stuck in the naughties. Sadly we no longer live in a world where we can burn electricity so frivolously.

The lights in your first link are ideal for actually lighting a room. Halogen are ok for display lighting, but better technologies of spot lighting are now available - compact fluorescent GU10s. TLC sell these

(Tip: you dont need fire rated stuff unless theres another flat above you)
These are a compromise, because they take 2 minutes to reach full brightness. One of the reasons they havent really taken off yet.

This is the real deal, PL downlights. The type of thing you see in banks, much better than GU10s. Instant startup at 80% brightness, full brightness within 30 seconds.

Any more Q's, ask.

PS, 12 of those 50w downlights = 600 watts. It dont take a genius to see that you could turn off your heating and it'd be warm enough.

Thanks Steve.

Those PL downlights are more or less what I had decided on.

Its just that I wanted a chrome surround, having trouble finding those.

Plan to get 6 for the kitchen of 4 x 4.5m.

Who else might sell?

JCC?

that explains HF better than I can.


JCC will have their own version of the atom. You can look. But I can personally recommend TLC for their prompt next day delivery (not now though, obviously, its too late for next day)

Thanks again Steve.

Just wonder why TLC didn't want to sell me these when I spoke to them!!

This would be the JCC wouldn't it?

or these

This is doing my head in

 

[Steve]

I think JCC only deal with trade. The second one looks interesting - same lamp, only vertical! But I think it'd be more directional light than the Atom.

The standard response for a request for "downlights for residential premises" is "halogen downlights". Its programmed into all their salesmen from birth. And old habits die hard. You'd think the electricity companies were paying them commision or something

 

[lisach]

Interesting?

Would 6 still be enough btw?

 

[lisach]

Would anyone be able to tell me how to calculate whether a particular Watt light equates to another?

10 x 50W GU10 type to be the same a 6 of these 18W?

Thanks again, sorry for asking

Its just that I wanted a chrome surround, having trouble finding those.

With Genura lamps in them.

 

[lisach]

How many for a 4 x 4.5 kitchen?

So these are better than Halogen or the PL's?

 

[ban-all-sheds]

I would have thought that 6 of them would be fine.

Definitely better than halogens, and what I think makes them better than the PL luminaires is that the light source isn't recessed, so you get a good spread.

Downsides are that they aren't dimmable, and the lamps contain the control gear, so are a bit wasteful.

 

[lisach]

Same as these are they not?

Pretty similar - same basic size/design/lamp type.
