Steve_hi Posted May 7, 2007 Report Share Posted May 7, 2007 Very little in life is free you will have to work at getting them. A company letter head and a projected sales volume will probably get them interested in giving you some samples but your presentation will have to look professional.Good luck ;)http://www.photowatt.comSend Email to Photowatt International S.A.http://www.npowercanada.comSend Email to Npower Energieshttp://www.china-solarpower.com/sdp/110301/4/main-1000013.htmlSend Email to Shenzhen Xinhonghua Solar-Energy Co., Ltd (Representative:Angel) Quote Link to comment Share on other sites More sharing options...
audioguru Posted May 8, 2007 Report Share Posted May 8, 2007 My electrical Utility gave away free solar garden lights. I got 10 of them.I can see them glow at night but they don't light up anything because they are dim.They have a single 1.2V AA Ni-Cad battery cell and a voltage stepup circuit. The dim LED is amber colour. Quote Link to comment Share on other sites More sharing options...
