STP 48 — Electric Signs — Two proposals for UL 48 covering switches not serving as sign disconnect and accessibility of through wiring, were circulated for ballot in December 2020, closing on Jan. 18, 2021. Both proposals reached consensus with no negative comments and will proceed to final publication.

The first topic related to battery-powered night lights did not reach consensus. The other two did reach consensus and will proceed to final publication in February 2021.

STP 496 — Lampholders — Two proposals covering ANSI C81.63 gauge references and screw shell base material options were circulated for STP ballot in December 2020, closing on Feb. 2, 2021. Both proposals reached consensus on the first ballot, with no comments, and will proceed to final publication.

STP 1598 — Luminaires — The proposed new fifth edition of UL 1598 was circulated for STP ballot in 2020. The proposal reached consensus, but with a significant number of technical comments.

  2. LED controllers
  3. Potting compounds
