Glad you got it sorted Al. I'll be interested to hear how you go with the replacement - I gave all our low voltage lights the flick years ago.

 

what did you end up doing quark, replace what with what ?

 

its something I need to think about since we will install probably another 5-6 of these things over next few years so better off making right choice...or better choice this time

Initially replaced with a mix of super-compact GU10 CFL downlights and conventional fluorescents. One of the GU10 CFLs died last year (after ~4 years) and I've been running a GU10 LED with integrated 240V stepdown electronics in the same fitting for the last 12 months.  So far so good

this sort quark ?

at about $6 ea... maybe am over the whole low voltage LED light with transformers malarkey !

 

theyre replaceable to. so blow one...no big deal toss it pop in another

That's the type - I bought Philips with a 10 year warranty - probably comes from the same factory.

^ Just so you know, those still have transformers in them.

 

Those 5W LED's don't operate on 240v AC.

yes so like conventional light bulbs can unscrew throw way screw a new one in. dont have to worry about transformers and going into the roof cavity to change the entire light fitting and bulb assembly and transformer as well. 

 

pros and cons for both I guess...but am seeing  lot of reasons to just go 240V LEDs next time

I rekon on you're on the money here @@betty boop, both my brothers have replaced some of there halogens with these CU10 LED assembly as a trial and none of them have had to replaced them, if they have to then like it is its $6-8 not $70. I was about to do the same as you don't need a transformer/driver/SMPS that adds to the power consumption of use. With the MR16 you need that SMPS to convert to low DC wattage that can add an extra 10w so at the moment all mine are 16w total for a single LED and I use 4 of these in on circuit, but via the government scheme they'll sit there until they come down to a reasonable price for replacement.

When LED 1st came out, IKEA had a range of them, I bought this one to trial for a lamp stand that requires no SMPS low voltage conversion for $12, I use it to watch TV as I have a large living area and it still going today:

All led downlights have a voltage transformatIon section and led driver (led current controller). The GU10 have the voltage reduction and current control inbuilt, the 12V downlights utilise the existing step down module (either iron core transformer or switching PSU)

In both inbuilt and external power supply implementations there are losses in the power supply, a SMPS has a typical efficiency of > 85%, a iron core has much less efficiency and can dissipate the same amount of power as the led itself. There is little to no difference in "lamp circuit power" comparing a GU10 5W led and a 5W MR16 led running off an electronic transformer (SMPS).

Lamp circuit power is the total power consumed by the luminaire/lamp including any in line control gear, and this measurement is used when assessing the effiiciency of the luminaire/lamp. There are two measures of the overall performance of a luminaire - efficiency and efficacy. Efficacy is the measured lumen output from the lamp/luminaire compared to the lamp circuit power consumed (lumens per watt) and the efficiency is the comparison between the native output to the light source (in this case the LED chips) and the actual measure lumen output from the lamp/luminaire. There is little difference in the lamp circuit power of a 5W LED with integral control gear vs a 5W led running off an 12v output electronic downlight transformer.

Thanks for the time taken to explained what I wouldn't have.

FYI, the 220-240V 5w E14 IKEA LED, from the pic of the previous post, measures 5.1W I'm not gonna discussed what luminance it produces but it's visually bright enough as an E14 compared to the incandescent

I just converted the 10 compact fluro bulbs in my wife's makeup mirror with LED bulbs

Well worth the $34 I spent

i did that to, now she looks much younger......

how long does it take to change a light bulb ? 

 

apparently nearly a month :lol:

 

as I worked out. Its not a case of "change a light bulb" as the LED lights I have ...have transformers and one of the transformers have gone. all investigation has found....no replacement transformer. IT would seem all LED lights that use transformers seem to use a type that suits the light itself. Since I cant find a replacement transformer it means I need to replace the light and transformer and replace with the whole assembly.

 

ok in all this searching I have to be honest I am well and truly over these two part light and transformer LEDs. So decided will replace with mains LED fittings that take a standard GU10 LED bulb...that can easily be replaced anytime one might blow....

 

in my searches I have to say led light fittings that take GU10 there seem to be a few around but gee some are just so average ...eg the osram ones and neither are they cheap....

 

and then I stumble across in IKEA....

 

 

wow only $11.99 and gee take a GU10 and is actually quite well made ? and the matching GU10 they sell is also only about $10 ? gee this looks good... so I buy a couple ....

 

anyways things have been busy...and once worked out what I needed and got what I needed I have been partly limited to when I can get up in the roof and its not sweltering !!! well 

 

 

Warm day today but made an early start,

 

and didnt take all that long to swap over ...and there is light ....

 

 

do a great job too...

 

so next time one of these blow ...it wont take me a month to change a light bulb !!!

@@betty boop,

 

at that price you can buy some spares and not live in poverty.....    

 

We done mate,  youre not going to believe this, I actually drive all the way from Point Cook just to check out lighting....at IKEA in Springvale of course!
