I've checked Beacon and the like but they all have the same fans from the same factory just branded differently. Anyone have "Eco" fans and were they a reasonable price, and by my standards over $250 for a ceiling fan is ridiculous. Cheers, Bailey.

Re: Ceiling Fans 4Jul 09, 2009 2:08 pm We ended up choosing Hunter Pacific Typhoon which are mid-range in price with the Verona Light accessory. It is also possible to spend several hundred dollars on just one fan: http://www.hunterpacific.com.au/products.html A word of advice: 1) The biggest price driver is probably the quality of the motor and bearings. After all the rest of it are either bits of metal or wood. Look for a good warranty. Going bargain basement in price is probably not cost-effective. 2) Err on the side of larger fan diameter (to the limit of aesthetics) Big fan = lower pm to achieve same airflow = less noise. Annoying draughts are less noticeable under a large fan spinning slowly than a small one rotating wildly. The cooling effects of fans are felt mainly directly beneath the blades. Air movement drops very quickly past the edge of the blades. 3) Choose one which can spin in reverse for winter (drawing air up). Some people say this is pointless but the difference is noticeable. Fans are not just useful for cooling. In winter they help recirculate warm air that inevitably stratifies toward the ceiling. 4) The problem with most fan light fittings are the lower light outputs achievable (particularly with an eco-fitting). The choices are also limited with either oyster style or spotlight. But there are usually eco-equivalents for any standard conventional voltage fitting e.g. GU9, GU10, mini edson screw, edson screw, bayonet. Some you can find in any supermarket or hardware store, some only from a light shop or special supplier. The limiting factor is usually if the bulb dimensions actually fits with a full enclosure. Some halogen GU 10 eco-equivalents may not look as aethetically pleasing if exposed if used in spotlight fitting. You can cobble any fitting (even a pendant) below a fan with a light connection. But if done badly, it just looks odd. If you decide to increase the light output in a large room, be careful of what other fittings you choose to fit around the fan. Pendants obviously cannot obstruct blade movement, if set too close they may also swing and knock when the fan is on. Downlights, oysters or ceiling mounted lights set immediately above the blades will result in annoying strobing. 5) Blade number is less important than blade diameter for efficiency (look at a wind farm windmill). There are some blade designs which are more efficient but these are difficult to find in Oz. Even the manufacturer data is a bit obscure about how well their fans move air. Operating noise is also dependent on blade type. Metal is noisier than wood but metal also moves air better (all other things being equal). Our Metal Typhoons only sound annoying at top speed.
