RE: CBus dimmale LED's

[Paul Gale <groups2@xxxxxxxxxxxxxxxx>]

I'm a bit confused now - do the dimming MR16's still need an LED
driver or will they work from an existing transformer?

I have old wire wound transformers that supply around 6 50W halogens each.

Is there a solution that allows just a replacement lamp (I guess with a
built in driver of some sort)? Or does the transformer definitely need
replacing? (the transformer replacement would mean taking down the ceiling
and fitting a new one - although that might have to happen anyway with the
changes to plumbing).

Cheers,

Paul.

OK cool - where did you get your megaman units from?

No sign of flickering at dimmed levels?

Hi Paul



My dimmers are universal in as much as I can set them to trailing or
leading edge depending on the attached load. The Megaman dimmable LEDs
specify leading edge dimmers so should be fine with your CBus units,
subject to minimum loading etc.

Thanks Neil.

Are your dimmers leading or trailing edge?

Mine are the older leading edge although I see that there's a 'universal'
CBus dimmer that does both leading and trailing edge from what I can see -
wondering if that needs to be changed?

Paul.

I use Helvar dimmers rather than CBus, but I've had good results with the
new Megaman 6W Dimmable lamps which were good value from Starlec online.
They dim nicely and are a nice warm white. I've also tried some Megaman
golf ball dimmable LEDS in table lamps which also work well. However I've
found that unlike the GU10 lamps, these do not go fully out when
"off" - I get a very dim output that is only visible in a truly
dark room (whereas the GU10s go fully off). I'm guessing the driver
electronics in the base of the lamp are different and this combined with
the electronic dimmer (as opposed to a wall-mount dimmer with a physical
switch operation) is causing the issue.

Has anyone here in the UK got CBus with leading edge dimmers and had really
good experiences of dimmable LED driver/lamps? I've seen a number of posts
on the CBus forums but they seem to mostly relate to Australian
parts/suppliers etc.

I'm re-modelling my kitchen and want good output, dimmable LED's for the
downlights. Limited budget though, so they can't cost a small fortune.

Any ideas/experiences?

Many thanks,

Paul.
