Fred99:
Without too much haggling, price came down to under $25, which for the brightness / dimmability / colour is OK. They certainly are bright lamps.
I've fitted the LEDLux dimmer. Has a small trim pot on the side which needed a bit of a tweak to get dimming perfect. Annoying place for the trim pot, as the faceplate has to come off to access it. It's also maximum 150w load - no minimum stated. No problem as there's only 40W on it, but if someone replaced the 3 E27 LEDs with >50w incandescents, I expect the dimmer might emit smoke. The cheap leading edge dimmers IIRC are rated 300 watts or more.
I needed to do this job now, but as time goes on and LEDs get better - especially the Philips ones which so far seem to dim well with standard cheap dimmers - I'll probably replace all the existing light switches with dimmers, and "over-specify" LED lamp brightness in each existing fitting. IMO the "right amount" of light is a very subjective and mood or activity dependant thing.
Follow up on that for the record - as I've found out that not all Phillips dimmable LEDS work with cheap dimmers. (The ones I had were "Goldair" - labelled that they work with "LED - Check specifications", only about $18 from Mitre 10, Clipsal insert type).
I've almost finished kitchen / dining renovation, has a set of three pendant lights over a bench with decorative Phillips E27 dimmable LEDs that were working fine with a cheap dimmer. Next to that dimmer switch I'd put in a second cheap dimmer, in the meantime was connected to a halogen light until i got a suitable light fitting.. Replaced the halogen light over the weekend with a pendant which uses E14 candles. Bought the Phillips dimmable E14 candles thinking they'd "just work" - but no - they were terrible, flickering and uneven dimming. Worse - when they were on, then the adjacent dimmer which was working fine started playing up, presumably some electrical interference getting back up the line.
Replaced both cheap dimmers with LEDLux dimmers from Lighting Direct. These are "on special" at the moment, reduced from about $65 to $48 each. They're working perfectly.
