They are electrically .. identical but optically somewhat different owing to differences in the lens. The NSL102 and NSLO002 have alight-diffusing plastic lens and differ only in the presence or absence of a red colorant in the plastic. Both appear visually as large-area, soft, light sources with wide-angle visibility. The NSL101 has a semi- diffused lens. It appears visually as a medium-area, soft light source, larger than a point source but smaller than the NSL102, and it has greater angular visibility than the NSL102. These devices are panel- mountable with a plastic adaptor clip. They are circuit-card mountable with the dark body colour x Bottom View offering excellent contrast.
