Agree 100%
Halogens are the most inefficent bulbs you can buy, since tungsten lamps were banned from sale.
But unfortunately CFL is not good for downlight replacements, and good LEDs are expensive.
Best to replace old-style downlights altogether - unless you obey the law and call in an electrician, who will charge you a lifetimes power saving to install the new lamps. No win.Why not good for downlights?
Yeah but the warm white colour temperature is a lot more natural and pleasant looking than god-awful CFL or LEDs which make every room look like a sterile laboratory.
I've got about 11 halogen downlights and replace them probably every 6-8 months or so (over a year for the less frequently used rooms). They're nowhere near as costly as people make them out to be. You can get 50W Philips ones with 90 degree beam angles; which is brighter and wider than any CFL or LED counterpart.
You can get LEDs in any colour temp you want. You do realise you must have just picked up the cool white ones?
And tour comment about brightness and beam angles is completely wrong as well. LEDs can have a far wider beam angle (I have seen 150 degrees +) and LEDs can be much brighter than 50w halogens
Please stop giving your 'expert' opinion just because you had a bad experience with the $10 LEDs from Jaycar. If you invest in good LEDs they are far superior than halogens in every regard
LED light bulbs are the long term solution now. Cheaper to run and last a lot longer.
upvoted id realy like to kinow what idiot dowvotes every good comment LED are the future atm unless they create something better.
Price?
Aldi sells them 4 for $4, not 50watt, 35/45 maybe. But for downlight that less wattage should be better.
I've tried the aldi ones and they are nowhere near bright enough. I'll stick with proper 50 Watters thanks
Don't look at the wattage. Look at the lumen(lm) output on the globes.
Old 50 watt downlight (MR16)(ones with transformer) were about 600-700 lumens.
The new 35 watt ones come in 2 ranges, a budget, and more expensive versions. Both use 35 watt, but the lumens are (435-460, and ~680)Cheap: http://www.bunnings.com.au/osram-mr16-35w-60-halogen-globe-2…
Expensive: http://www.bunnings.com.au/philips-680lm-35w-gu5-3-eco-halog…
So there is no reason to buy the 50 watt globes.
Thanks for the info hothed.
The Philips one that you linked - it says in the description that "Dichroic reflector coating transmits heat towards the back and light reflecting to the front of the globe"
Of all the things, why would you want to transmit heat towards the back? Aren't downlights already known to be a fire hazard anyway, I don't get why heat should be transmitted to the back where there is no ventilation? :S
Theory goes for IRC Halogens, Heat is reflected back to the the filament.
More heat = more light.
A bit like a Turbo on your light.
Does anyone know where I can buy Phillips L Prize LED bulbs in Australia? All I see are the 120v ones in US.
I have GE 50w halogens that i have just replaced with 8w Nichia Leds. (3000K, 60 degrees)
Some of the GE halogens were over ten years old and were in use daily in the lounge room with still higher brightness than the Nichias.
Howerever, happy with the Nichias now as no heat issues and less power consumption with payback within 1 year.
bought them from ebay,

If you really want to save money, buying halogen globes aren't the way to go.
