A lamp housing comprising:
- plurality of outer channel sections;
- internal light baffle means arranged between said outer channel sections;
- interlocking means on said outer sections and said baffle means for assembling said channel sections in mutually parallel spaced apart relationship forming a tubular structure with longitudinal ventilation slots between said channel sections;
