Dimming down lights

[steptoe]

thanks GS

I thought I was beginning to miss something so obvious,

everyone else was just answering you and I was still trying to get my head around numbers of lights.!!!!!

one of them days for me I suppose,

problem is,

more days are getting like that for me now, :|

I`d also look at remote dimming packs mate. The "bonus" advantage is that you can build scene dimming into this, minimising the number & complexity of switching.

As an extra; putting a few high-loaded grid dimmers adjacent can have detrimental heat effects. Some of those dimmers state a maximum PLATE wattage - i.e. the most you can have in total.

Cheers KME.

I have noticed that the maximum rating for some grid switches reduces to 200w when alongside others in a grid switch.

I have had a look at CFL downlights. This would reduce the load on the dimmers. However cost is an issue with dimmable CFL's.

LED is another option as already suggested. Cost once again is the issue.

I think I will have to go down the CFL/LED route. This will ensure the installation complies with part L and will solve the dimming issue. So, can anybody recommend any dimmable (cheap but not carp) CFL's/LED's?

It's always about the cost! If I had my way I'd stick a load of Collingwood dimmable LED downlights in!

 

[kme]

Dimmable CFLs aren`t really cheap, wherever. Megaman are probably the best I`ve used to date.

Similarly with the dimmable LEDs. The best I`ve seen / used were Aurora "cree" units; but they`re silly money (we didn`t buy `em, but iirc they were about

I can do a 7W dimmable GU10 LED brighter than the Phillips equivalent for around

 

[batty]

Megaman cfl's are a nightmare to dim you will be amazed at the size of dimmer needed and most standard dimmers won't work i have generally used richmond dimmers which work ok to a certain extent but if you dim them down to much generally one or two will go completly out the other option would be the dors dimming cfl's which dim down in four steps but that may not be what customer wants. As for led as KME says i think they are still to pricey for dimmable ones but i would put forward running costs to your customer and also maintanance if they do go for halogen. Maybe get a lighting engineer involved they may have a few suggestions.

How about something like thisJust googled "remote dimmer pack"

Are you not bothering to comply with Part L of the building regs then?

Sorry steps. I mean 3 rows of 12. Each dimmer controlling a row. GS---------- Post Auto-Merged at 22:42 ---------- Previous post was made at 22:38 ----------

Does it apply to rewires noz? Gs

GH,All the appropriate building regs apply to any alterations that are being carried out to a building

I just spoke to a Building Controller today,,, checking up on DL's.

I was reliably told that Part L does not apply to existing buildings and extensions to existing buildings as far as energy saving lamps are concerned.... only applies to new builds apparently:O

SO,,, GS I humbly apologise:coat

 

[kme]

S`okay mate - I`d have gone with your answer, too. So I was wrong, by association :coat

Cheers Noz. So basically on this particular job it's up to the client what type of light fittings they want installed, even if they are not energy efficient.

[batty]

Thats it but i would just tell them how much they cost to run they possibly may have second thoughts but some people have money to burn.

 

[gselectrical]

It may be specific to the areas building controlI had a new kitchen roof put on and they said I had to have those part L compliant energy saving lamps fitted in the new roof even though it was an existing extension. Went for the Haler dimmable LEDs which are very good.

Got a link to them fittings mate?

 

[wozz]

What dimmer did you use canoey? Ive had nightmares dimming Halers in the past.

 

[wozz]

I fitted the original halers dimming range and I could not get a dimmer to work, tried two recommended by them neither worked. Ive yet to find anyone that did! I think they have made a dud product.

Fitted the Halers H2 on a recent job but not dimmed them as yet.
