BAN the Incandescent Light Bulb - Use Compact Fluoro or new LED Light Bulbs!

As at 14 July 2009:

* Standard power price of NZD$21.77 c per 1kW unit
* 100 W incandescent light bulb at NZD$1.28 each
* 20 W Philips Compact fluoro bulb at NZD$15.99
* 13 W EarthLED bulb at NZD$110.49 each (Based on purchasing 8 bulbs + freight to NZ from USA: USD$407.99 = NZD$883.97)

Your Choice; 50,000 Hours of 100 Watt Light By Using:

* 50 incandescent light bulbs @ $1088.50 + $64.00 = $1,152-50 cost to YOU,
or/
* 8 compact fluoroscents @ $217-70 + $127.92 = $345-62 cost to YOU ($ + mercury poisioning) & the environment,
or/
* 1 EarthLED bulb@ $141.51 + $110.49 = $252 cost to YOU (and did I mention no mercury, and 50,000 hours is 34 years! :-)

Bit of a 'no-brainer' in my opinion - save anywhere from $900 to $93.62 per bulb (i.e. in our house we will save a massive $36,000 dollars... Wait a minute! That is the cost of the PV solar on my roof - I can go purchase some more for that price!! (Or a new car!)

This is exciting stuff! Finally there is available a RANGE of different LED based lamps / bulbs to directly replace nearly every single bulb in your house! From fluoroscent tubes (typically 4 or 5 foot long used in your garage / kitchen), through to bedside lights, to wall wash lights, to downlights, to floodlights for outside... Up to now these didn't exist, let alone easily purchase them and have them delivered to your door here in New Zealand.

(NOTE: In New Zealand you cannot get a 13 watt CFL that puts out the same light as a 100 w - you need to purchase a 20 W version)

5-7 Heat Collector Hybrid (prototype; power output=52Wp/m2)

5-6 Slide-In Type (prototype; power output=62Wp/m2)

PV module is placed in the heat collctor bx. PV module is bent into step shape in order to enhance heat transmissivity. Measurment of PV power output and heat collection s unerway on the roof of PLEA Press Center in Kusiro, Japan.

Fig 8 (top) shows the standard highway soundproof wall in Japan. PV modules are fixed by three different methods using dual surfae adhesive tape or screw or blind ribet. The evaluation is in progress by NEDO (New Energy And Industrail Technology Development Organisation) in Japan.
Fig 8 (bottom) shows another type of installation. 4m long PV panel is bent into triangle shape and screwed down to the top of soundproof wall.

PV panels is installed just by sliding i C channel and by sliding fastener member in C channel. Time saving installation become more advantageous as the scale of PV array becomes large like PV power statio. Panel can be replaced easily.

Concluding Remarks

LED based light bulbs in many different shapes and sizes that work in wide variety of voltages (110VAC to 240VAC to DC) are now commerically available at affordable prices... Is is expected that this will open a new light bulb age.
