it wasn't 20 minutes after clamped that damn thing down when this happened. I went down stairs to clean up my mess after a transplant smelled smoke and found the light laying against the lower shelf. there was no flames thank God but there was some red hot coals spreading and when i dumped the water on it in a panic the ashes dripped on the side light and all over my new widows. that was my second of three heartbreaks in the matter of two months
