Getting fixture spacing right is the single biggest lever on both installation cost and long-term energy spend. Too many fixtures and you overspend on hardware and power; too few and you fail the uniformity requirements written into most warehouse safety standards.
The industry rule of thumb is a spacing-to-mounting-height (SMH) ratio between 1.0 and 1.5. For a 10 m mounting height, that means fixtures placed 10–15 m apart. Narrow-beam optics allow the wider end of that range; wide-beam optics require tighter spacing to avoid scalloping on the floor.
Open-floor calculations fall apart once racking goes in. In high-density racking layouts, aisle-aligned linear fixtures almost always outperform a uniform grid of high bays — you light the aisle where people actually work rather than the top of the racks.

Here is what buyers need to check before specifying.", "content": "DLC 5.1 raised minimum efficacy thresholds across nearly every product category and tightened the controllability requirements. Products listed under 5.0 do not automatically carry over — they must be re-tested and re-listed.
Utility rebate programmes in most North American territories reference the DLC Qualified Products List directly. If the fixture you specified was listed under 5.0 and has not been re-qualified, your rebate application will be rejected at review — often months after installation, when the budget has already been closed out.
Request the current DLC listing ID and verify it yourself on the DLC QPL portal. A datasheet claiming \"DLC listed\" without a live listing ID is not sufficient evidence for a rebate submission.
All fixtures in our current catalogue carry active DLC 5.1 Premium listings. Contact our team for the full listing reference sheet.

140 W low-temperature-rated LED high bays with integrated motion sensors, rated for continuous operation down to −40 °C. Fixture count dropped from 312 to 268 thanks to better optical control.
Standard LED drivers derate badly in freezing conditions. The specification hinged on sourcing drivers with a genuine −40 °C cold-start rating rather than a −20 °C operating rating — a distinction several competing quotes glossed over entirely.

Higher is not automatically better — it is only better if your environment demands it.
The most common costly mistake is specifying IP65 for a food processing plant. Standard IP65 gaskets will not survive repeated 80 °C steam wash-down, and fixtures typically begin failing within 18 months — well inside the warranty period, but with the failure attributed to misapplication rather than defect, leaving the buyer uncovered.
Moving from IP65 to IP66 typically adds 8–12% to fixture cost. Moving to IP69K adds 25–40%. Against the cost of a full re-fit two years early, the higher rating is almost always the cheaper decision where the environment calls for it.
