Frequently Asked Questions

Compare by lumens, which measure actual light output, watts only tell you how much power a bulb consumes. A lower-watt LED can produce the same usable light as a much higher-watt bulb, so lumens give you a more accurate comparison when selecting a replacement.

5000K refers to correlated color temperature, which describes how warm or cool the light appears — 5000K produces a bright, daylight-style white that works well for visibility in barns and work areas. It does not affect energy use or output, just the appearance of the light.

No, dimmability depends on the specific product and whether it's paired with a compatible dimmer and driver. Check the product listing before purchasing if dimming is part of your setup, and confirm that your existing controls are compatible.

A vapor-tight fixture has a sealed housing that keeps out dust, moisture, and contaminants — making it the right choice for enclosed barn spaces, wash-down areas, or anywhere with high humidity. Standard fixtures are not designed for those conditions and will degrade much faster.

If the fixture housing and lens are still in good condition but the light has failed, replacing the driver is often the faster and more cost-effective fix. Zeiset carries a replacement 60-watt LED driver specifically for the 4' vapor-tight light.

A dusk-to-dawn light uses a built-in photocell to switch on automatically at nightfall and off at sunrise, making it a practical choice for barn entrances, equipment yards, and outdoor walkways. It eliminates the need for manual switching and ensures consistent exterior coverage overnight.
