Other savings from utilising the SP LED 3W MR16 include:
- Shock proof and can be 99% recycled.
-  Light output 800 lux@1m - Cool White 6000K (Daylight is 5800K) with up to 94% less power use
- Colour range - Cool White and Warm White available, and other colour options.  (See Kelvin colour range chart to the left)
Compared to 1 x 50w MR16 HALOGEN, the following annual savings could be achieved by utilising our SP LED technology, (1 x SP LED 3W MR16 @.14c/kw @ 14hrs/day).
- CO2 Emissions savings - 0.26 tons/year; (1 mature tree would be needed to compensate the environment with this amount of CO2 emissions - just from one 50w MR16 Halogen light).
- Bulb life of up to twenty (20) times longer than 50w MR16 HALOGEN - saving costly labour and outlay of HALOGEN bulb replacements.
- Power savings of up to $34/year.
- Economical replacement cost. (Payback time approximately 14 months from power cost saving excluding rebate).
- Low heat output reducing airconditioning power costs by up to 10%.
- light output 800 lux@1m - Cool White 6000K (Daylight is 5800K). with up to 94% less power use. 
- Power load reduction on the existing transformers, reducing power, heat, and making the system more stable. ie: SP LED 3W MR16 will not tend to trip out the transformers, which turn off when overheated by 50w MR16 HALOGENS. (New light fittings can use a much smaller transformer saving more power and initial set up costs)
- Government rebates can be available through the NSW Building Sustainability Index (BASIX) 2004 - see website: http://sustainability.nsw.gov.au/information/tutorials.jsp  or BASIX Help Line: 1300 650 908
- SP LED 3W MR16 has an operating voltage of 12VAC and 12VDC with the one fitting.
