Older or less common products

If your product or purchase date isn’t covered, please call technical support on 02380 982022 (option 2) or use our contact form. Our archives go back to the original UMSUG releases, and we can issue the historical code on request.

Photocell options

INDO luminaires can be specified with either a third-party photocell or an INDO integrated photocell. The two have different wattage and so different UMSUG codes. Pick the option that matches your unit, or use the photocell selector to see both side by side.
