RE: White/coloured LED bulk buy?

["Rob Mouser" <rmouser@xxxxxxx>]

Now I have nearly completed the downstairs of the barn my mind is
drifting towards lighting the hallway, it has a very high ceiling as is
galleried. We were planning to place a large number of small halogens in the ceiling to create an almost 'stars at night' look.

How easy is it to implement these LED's do you need a
transformer/controller?
Can they be dimmed (Would need to be with Clipsal C-bus)?
What is the lamp life of them?
How does the intensity compare to say halogen or incandescent lights?

Sorry for so many questions!


Many Thanks
Rob

Nope, nothing happened to my knowledge.

I need some for lighting my daughters cupboard in blue and white. Since
I
have a pressing (wifey) need for these I could be persuaded to organise
something.

Assuming the prices are as the web page who would be interested and for
what
colours and how many?

Money: I assume as per the norm money would have to be up front. I am
not in
any great hurry to get some as long as something is seen to be happening by
Wifey. When the time comes I expect to pay by credit card. When I have
an
idea of numbers I will also check out the local companies to see if they can
match or be close to product or price.

This is a summary of the web page. If there are any savings on the
quantities we order this will be passed on. Don't forget the import
duty,
exchange rate, VAT, postage and any costs I have forgotten.
