LED Lighting product family logo

C'est ce que (None provided) recherchait dans leur logo design

We have a new product line a range of high efficiency very bright general LED lighting products. I am looking for a eye catching logo to go along with the trademark name "GreenLight" the logo should convey a "green" feeling as environmentally friendly or beneficial and light obviously to illuminate. we have a new domain www.green-light.com.au so the logo will also need to be web suitable. I am looking for simple but distinctive.
The logo does not need to have text associated with it. The products are to be marketed in Australia and maybe New Zealand Voir plus
