Match Hikari 1580 / LU150/M, 150 W / 55 V high-pressure sodium, ANSI S55, and the E26 medium base. The fixture's line voltage is not the lamp's operating voltage; the ballast must be specifically rated for S55.

Fixture & ballast compatibility

Compatible-fixture references

Compatibility requires all of the following: a 150 W ANSI S55 high-pressure-sodium ballast, an E26 medium socket, adequate ED17/B17 clearance, and fixture approval for the lamp enclosure type.

  • Architectural HID fixtures explicitly rated for 150 W, 55 V ANSI S55 lamps
  • Industrial HID fixtures with an E26 medium socket and ANSI S55 ballast
  • Roadway and cobra-head fixtures with an E26 medium socket and ANSI S55 ballast
  • Street-lighting fixtures explicitly calling for LU150/MED, LU150/55/MED, or S55
  • Commercial area-lighting fixtures with sufficient ED17/B17 clearance and an ANSI S55 ballast
  • Open or enclosed fixtures only where the fixture manufacturer's lamp-enclosure rating permits the selected lamp

Documentation & safety

Documentation

A current public Hikari manufacturer datasheet for item 1580 was not located. The exact S55/E26 system match is corroborated by the lamp designation and established cross-reference data. For fully manufacturer-documented options, see the GE and Sylvania alternatives above.

Installation and disposal

  • Use only with a compatible ANSI S55 HPS ballast and properly rated E26 lampholder.
  • Use a 4000 V pulse-rated socket where required by the fixture or lamp manufacturer.
  • Disconnect power and allow the lamp and fixture to cool before service.
  • Protect the lamp from impact, scratches, moisture, and combustible materials.
  • This HID lamp contains mercury. Follow applicable lamp-recycling and disposal requirements.

The Hikari page intentionally limits product-specific claims to the established catalog identity and flags inherited measurements that lack a current public Hikari datasheet. The fixture and ballast labels remain controlling.
