I am in the future going to try and find good quality leds for my home. We have chandeliers in the bedroom and the bulbs put out horrendous rfi. What brand or set up should I look for?

I can't comment much on interference as I am already in a bad part of town when it comes to radio and television transmissions. I live in Sydney's cancer triangle on the North Shore, smack bang between the three large TV towers and when driving past these it blacks out AM radio transmissions to the car radio, which come from only about 10km away as the magpie flies.

My house has LED globes in every room. All were purchased from Aldi about four years ago and all are still working well. The kitchen is an exception - it has LED replacement fluoro tubes purchased at Bunnings and these are still working correctly after about two years. These tunes are 4000K but the globes are 3000K, which better mimics the output from an incandescent globe so the light output is good from only 8W.

I've tong-tested these globes and the fluoro fitting to make sure that all lamps consume only their rated power consumption.

An interesting (perhaps) observation: New LED ceiling lights, twin setup, to replace crap twin fluro with electronic ballast that died quickly like several others. The measured OP in light shows this I think 43 Watt LED job putting out more light than the twin 2 x 38 watt one & its got a frosted cover.

I am not really concerned about how cheap they are but will they last a long time with no interference. What brands are the best.

As I mentioned in a previous post, I bought a batch of LED 'globes' from Aldi and they started failing immediately. The 'best' lasted about a year. All have failed now and in each case it was the power supply that died (with the usual burnt resistor smell). I have not checked the mains voltage at my house lately but it may be closer to the old 240V than the 'standard' 230V. Given that the European mains is 220-230V then the 'made for Aldi' globes may have been at the higher end of their range.

Since then I have bought different LED globes from Coles (Jamison) and there have not been any failures with these. The globes are Mirabella brand (made in China) GLS 1400, 15W Warm White, 2700K. The packaging claims that these replace a 72W halogen and should cost about $8.54 per year at 26c/KWH to run when used six hours a day. These globes are slightly bigger and thicker than an old incandescent globe but will fit into all my bayonet housings. So far I have not had any RFI issues on AM.

To provide a 'benchmark', my house is just 30 years old now but the florescent tubes in the two bathrooms and the garage are the originals. Five of the nine exterior lights still have the original incandescent 60W globes. I tried replacing the four that burnt out with CFL but found that these would not operate once the temperature dropped below about 10 degrees C which is not unusual for a Canberra winter evening.

Have a read up on the effects of LED lights before you decide to buy them , There are many sites on the Net that speak about the concerns of LED lights . I did have my house running only LED but ive gone back to incandescent for many reasons , My eyes and sleep has thanked me for doing so , Also I find LED lights cause interferance with my old radios and cause reception dramas . pete

The globes that I got from Aldi were LUCE Betta GLD045 16W. From my experience I would NOT recommend them.

The good quality LED modules come from Cree in the US, Nichia in Japan or Osram & Philips in Europe. Some Chinese manufacturers use these and others just use whatever is available and build down to a price.

To be honest, and referring to the original question of interference, there's no real test available and one would need to purchase on gut instinct and try a certain brand of LED globes and just see what happens. Going by the way things are made these days and the lack of determination by the ACMA to mount an offensive against garbage imports I doubt there is a LED globe, or any other electronic globe that doesn't spew interference.
