- Features
| 9.0IN Length |
| HID is generally the most efficient light source |
| Better efficiency almost always means lower operating cost |
| Most HID lamps have life ratings that are better than incandescent lamps and similar to fluorescent lamps |
| An HID lamp produces high light output from a relatively compact source |
| Like incandescent, it is a point light source, which allows for good optical control |
| High color rendering (65 to 70 CRI), much better than standard HPS |
