400 W High Pressure Sodium Lamp

The SYLVANIA 67533 LU400/ECO is a 400-watt high intensity discharge lamp built for street, area and industrial lighting. It delivers 2100 K warm amber output with a 22 CRI rating and a 24000-hour rated life. The E39 mogul base fits standard HID fixtures and the lamp passes the Federal TCLP test for reduced hazardous waste.

Universal burn position E39 base

The ET18 envelope screws directly into any E39 mogul socket and operates in any orientation without a separate ignitor. Install only in a fixture rated for 400 W high pressure sodium with the correct ballast; mismatched ballasts cause cycling, low output or immediate failure. Handle the clear outer jacket with clean gloves to avoid hot spots that shorten lamp life.

Verify ballast and fixture rating

Confirm the existing ballast is marked for 400 W high pressure sodium and that the fixture is enclosed and rated for the lamp’s operating temperature. The lamp is not compatible with metal halide, mercury vapour or LED retrofit ballasts. Ensure the supply voltage matches the ballast specification before ordering.

Questions about this item

How can I confirm the LU400/ECO 400W lamp is operating correctly after installation?

The lamp should strike and reach full 2100K amber output within a few minutes, run without cycling, and deliver its rated 24000-hour life when used in a compatible 400W HPS ballast.

What comes with the SYLVANIA 67533 LU400/ECO bulb and what must I purchase separately?

The box contains the single ET18 clear HID lamp with an E39 mogul base; a 400W high-pressure sodium ballast and an E39-rated fixture or socket must be supplied separately.

Which version of the 400W high-pressure sodium lamp should I choose for my application?

Choose the LU400/ECO ECOLOGIC model 67533 when you need a 400W, 2100K, CRI 22 lamp that passes the Federal TCLP test and fits an E39 socket in universal burn position.
