Hi All

 Was in home depot , and found some interesting LED lights , and have some pictures of a power up test - see my link to photos the cost was about $9.00 CND probably cheaper in the US . I thought wow have to test these , depending on the scale of the plane might work out great.  Note there is one other configuration of the light same diameter , but wider. Added photos of the other LED light see photos at link. 

Few people have asked about measurements all in inches
