Am I wrong to install 28 downlights?

[mylocalplumber]

Hello sparkys,

I just bought the hbouse to raise the family and doing alot of the work myself. Before you start, I wouldnt dare mess around with the electrics apart from maybe running some cable to save costs for sparky.

Know I had planned to to install downlights in living room and kitchen which is open planned (now I've knocked the wall down.)

I just assumed downlights were the fancy, good looking way to go and have always liked the look.

Now I'm hearing otherwise so..please..can you convince me not to go for them.

I am buying 50w Aurora lights..and was planning to have 20 of these lights off a 400w 3 point dimmer - thats not gonna happen is it?


Now all these lights will be adjustable so that solves the shadow/beam problem doesnt it?

Lastly - should I get sepereate transformers for each light or can I run a few off one transformer?

Gonna talk to my sparks next week but I'm just impatient.

Know I've asked some silly questions but go easy on me eh?

Speak to your sparks before you start running any cables in as you could be wasting your time and money.

Personally I'm looking at staying away from the Low Voltage down lights now, the advances in the LED technology is fantastic and even if the dimmable LED stuff isn't the cheapest yet its getting there, and the GU10 mains voltage stuff is the easier/cheaper to retro fit further down the line as you won't need to change anything other than the bulb.

Another thing against the Low Voltage stuff is you may need to spend a fortune on a dimmer. I generally find if you have 400W of Low Voltage Halogens, you need an 800W dimmer. Have never had a problem with the mains voltage ones though.

Personally I'd strongly think about the LED option, it will be much cheaper to run and maintain but it's going to be a big outlay on lamps.

I second that.
Use GU10 fittings and then, when the price drops use the latest LEDs. The light is now comparable with 35W halogen lamps.

hmmmmmmmm

50w X 20 = 1000w
the 400w dimmer is to small

re-transformer

you can either get a spider transformer (prewired with multiple cables going out from it (DO NOT CUT THE CABLE SHORT, IT WILL BLOW THE TRANSFORMER)

I would suggest separate transformers, if one blows, you loose 1 light

I think that you better get your spark in to help you - and also I'd be thinking about have multple switchesso you don't have to have too many on at once.

Unless the kitchen diner is the size of a 5 aside football pitch!

second above posts. GU10 fittings with LED lamps. i would not use LEDs of less than 5 watts (each), as anything less will not give sufficient light. with halogen spots, it's not only the running costs, but heat dissipation is a major headache especially if some muppet has stuffed insulation above.

Fit as many GU10 enclosures as you like. Spend £300 on LED lamps, at least your cieling won't get too warm!

Seen many transformers wrongly installed/overloaded. Great source of ignition!

LED lamps are cost neutral after 12 months due to using much less energy than standard GU10s.

Don't go below 4 watts as the quality of light output is far from impressive. Link below detailing T8 tube comparison. Gives info on watt/lux/lumen values.

Some LED lamp manufactureres make elaborate claims on what their lamps will do. I would guess a decent Wholesaler will let you try a sample if you are going to buy 28 lamps from them.

1.4kW , i light the whole house for less.

You know me too well Tel I hate these blithering things. Until the advent of LED I never could understand how these things got approval to be fitted into a solid ceiling without ventilation or a large space above them.

They were Halogen lamps and to me it was literally putting mini heaters into a ceiling ....................and don't start me on the light spread lol

 

[telectrix]

don't like that light spread. always butter for me. LOL.

HALERS Evolved need I say more? go to their web site n see the cost/life savings the light output is as good if not better than 50w gu10 they are dimmable and 7year warranty Cost a fair bit to start with but over the years of no lamps and a fith of the power soon saves dosh

Thanks for all your replys,

Well I'm still not decided but have given myself these options. Oh and the downlights will cover a living area into dining area and kitchen.

1. Have pendants and uplighters in living and dining area and downlights in kitchen and bathroom
2. Fit 12v downlights for whole area
3. Fit 240v downlights for entire area and upgrade to led when cheaper.
4. Fit pendant in living room, downlights in dining area and kitchen.

I took down old lath and plaster ceiling so its a good opportunity to have downlights installed but if pendants are way forward it would save a bit on cost

Cheers

go down the GU10 SMD led route the new ones(they look like little flat squares with yellow dots when you look at the lamp and are very bright) bit expensive to start with but it they get left on by the family at least they wont eat the elec.
