Engineering reference
Choosing the right LS-VT configuration.
Confirm the target level at working height and set the wattage accordingly — all three settings ship in the same fixture. The 110° opal prismatic lens is the only optic documented for this family, so if the application needs a narrower distribution, the CIT families are the alternative.
LS-VT trades the CIT platform's lens choice for field-selectable wattage in a single 4-foot body. Where a project needs one part number across areas with different light-level targets, the multi-watt switch does the work that separate catalog numbers would otherwise require.
Common questions
Frequently asked questions
These answers clarify the selection process without replacing project-specific documentation.
What does multi-watt mean on this fixture?
The table documents 40 W to 60 W as selectable settings within one fixture rather than separate models, so a single part number covers the range. Confirm the switching method on the specification sheet.
What operating range is documented?
−4 °F to 104 °F, alongside a 50,000 hour rating and DLC Premium listing. Confirm against the ordered configuration.
