Frequently Asked Questions

How long is the nominal 4-foot cooler light?

The fixture measures 44.88 inches (1,140 mm) overall, including end caps. The 4-foot designation is its nominal size, not its measured length. Check the actual dimensions against your available mounting space before ordering.

Is the 36-inch lead wire already attached?

Yes. The fixture comes with a pre-installed 36-inch lead wire. The installer connects this lead to the 120–277V AC power supply.

How is this fixture installed when replacing fluorescent lighting?

This is a complete LED fixture for replacement or new installation. When replacing fluorescent lighting, bypass the existing ballast and lamp sockets and connect the fixture directly to 120–277V AC power using its pre-installed lead wire. Have a qualified electrician perform the installation with power disconnected. The fixture is non-dimmable. Loosen the mounting nuts to rotate the fixture and aim light toward the merchandise, then tighten the nuts to secure the selected angle.

Can this light be used in refrigerated or freezer displays?

The fixture is designed for refrigerated displays and is specified for operating temperatures from −4°F to 122°F (−20°C to 50°C). Use it in a freezer display only when temperatures remain within that range. It is IP44 rated; confirm that the installation environment and cleaning conditions are suitable for that rating.

Can the 4-foot model be daisy chained?

No. The 4-foot model has a single pre-installed power lead and does not support daisy chaining. Within this GLT cooler-light family, the 6-foot model has the Y-cord with male and female 3-pin jacketed connectors for linking.

As I just wrote , when I originally looked at these bulbs it said free shipping. When I got to the actual purchase order there was a 39.99 charge for shipping. And then as an incentive for further purchases again the email said free shipping.
