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.

not trying to hijack, but does anyone know if there are any LED bulbs to replace "halogen" bulbs that look like the one below? or is it impossible to make one? (the light fixtures are built into/is part of the house, unchangeable)

Tried a few, they all have sucked and had noway near the light output of even a basic 20w CFL, 2 of them had bad flicker and one had wiring so dodgey that it probably had the heatsink live when installed.

Sure.  Even available here in NZ but price (NZ) is not pretty

 

I bought one locally from Lighting Plus last weekend for an outside fitting high up on the house.  Was recommended by them after I showed them a photo of the position of the fixture.  Cost $35 for a 9w J118 bulb :( 

 

But when I got home I realised it was non-dimmable and only about half the lumens of the existing halogen bulb. Would have been too low powered for the position of the light.  Fortunately had not opened the packet so was able to take it back.

 

 

 

Have instead purchased three off eBay - about a quarter of the cost (~NZ$9 each incl delivery) for a 20w dimmable bulb (~1600 lm)!   Given the eBay prices, I also ordered another six J78 bulbs for internal lights.  Cost for these is ~NZ$5.50 each (12w, ~1000 lm, dimmable).  Electricity cost for the remaining life of the existing 100w halogen bulbs will far exceed the cost of the LED bulbs.

 

Only ordered a couple of days ago so not tested yet.  Not expecting any issues though (all 220v).  Potentially up to a month before they arrive but not an issue as still have working halogen bulbs in the fittings.

 

One point to be aware of.  The LED bulbs have a larger diameter (19mm for ones I bought) than the halogen equivalents.  Not a problem for our light fixtures though - plenty of space around the bulbs.

 

 

 

Hundreds of options on eBay.  eg. https://www.ebay.com/sch/Light-Bulbs/20706/i.html?Type=LED&_dcat=20706&rt=nc&Bulb%2520Shape%2520Code=R7s.

 

The 118mm ones I bought were from this place http://www.ebay.com/itm/152631115056

 

Bought the 78mm from a different place but the specs for them are identical to the 78mm bulbs on the above site.

 

 

 

The bulbs I bought were 'warm white' (2700-3300K).  Would have preferred 4000k but very few available for this type of bulb - not certain I found any that were 220v and dimmable.

Wow thanks that would be life changing! Just can't stand the power consumption of the current bulbs.

 

When you say it should be OK, are you basing that on the seller's feedback? Richms seems to think they are no good.

 

BTW I don't need dimmable, my fixtures have no dimmer.

Wow there are like a million different options, all using about 3-4 stock pictures.

 

They look very different to the halogen bulbs - can you tell whether they are good or bad based on how they look externally (assuming the pic is accurate)?

What size do you need? Measure from end to end. I've got a couple that I don't need any more because the fitting fell over and broke - nothing wrong with the bulbs.

 

The output isn't super high, but one is enough to light a room say in the evening when you're watching TV.

The gel encased ones were some of the worst looking output and flickery lamps I have ever seen. I dont think there was any smoothing capacitors on the board at all.

 

Also the numbers on any ebay listing for output and wattage are generally totally BS, so you will probably find when it arrives that the "9w" light actually takes about 5w and is as dim as a candle.

Yes, will have to wait and see how they perform but cost is minor so worth the punt (ie. given that one under powered NZ bulb that is not dimmable cost $35, more than the total cost of the six J78's I bought off eBay).  Besides very hard to find these bulbs in NZ (did not find any dimmable LED's of this type)

 

 

 

I bought one other set of LED bulbs off eBay about 17 months ago (E27 corn bulbs, ~$8 NZ for four bulbs, a fraction of what they would have cost here).  They perform pretty much as specified.  No flicker I can detect, unless attempt to use the dimmer (they were specified as not dimmable).  Could not find dimmable ones with suitable dimensions at the time.  In an office so never used the dimmer anyway.

 

==

 

Had previously replaced some MR16's (GU5.3) with NZ sourced LED's but all our existing MR16's are 12v and about half of them on the end of a dimmer.  The NZ sourced bulbs perform well (better light than the halogens they replaced).  

 

But problem is have to replace the transformers as well as the bulbs or change to 240v versions.  Not so simple and expensive when have multiple individual recessed bulbs in ceiling of a lower floor (one transformer per bulb).  Changing to 240v LED's means have to replace the existing fittings so is also expensive (about the same as replacing bulb + transformer 1:1).  Upstairs has roof space access so can link 2+ bulbs per transformer so that option is cheaper there.  

 

Yes some 12v 'retro' models can apparently be plugged into (most) existing halogen transformers but they are expensive.  Most have large vents & protrude below the fitting (low WAF).  More critically, all the 'retro' ones I found have 36 degree beam angle, which is not suitable for our situation.

 

The MR16's I replaced were not on a dimmer and were multi-bulb fixtures.  I replaced the fixtures which meant I could use 240v LED's.  That was an *expensive* operation though, justified only because those lights are in our main living area and with people here all day, are on ~10 hrs (ave) almost every day.

Bought some Philips LEDs from Bunnings yesterday and 9W was brighter than our 24W energy savers. Amazing stuff.

You can get a gu10 cap and wire and box for very cheap if you want to change to gu10 lamps. So long as the wire will reach you are good to go. The ones I got had a metal bracket to hold the junction box off the spring mount for a normal downlight too.

Advice I got is that 240v lights must not be swivel type.  All our MR16 fittings are swivel type so require all new fittings to go to 240v.  Added issue is that the 240v fittings I located were white only, which would clash badly with the colour of our ceilings

Ebay, no brand. From memory I think I have one 78mm and two 118mm.

Hi so sorry for the delay, my brain works on a high latency (wife always yells at me for being silent when she talks to me) and mega time delay (don't get me to fix your broken toilets).

 

I've just measured today, it's 78mm. I need 6, I think I'll go the ebay way. Thanks very much for the offer, much appreciated.
