Key Benefits + Pool Light Upgrade Fit

  • Replaces a compatible incandescent pool-light bulb with color-changing LED lighting
  • Provides seven solid colors and five programmed light shows
  • Uses an existing compatible ON/OFF wall switch to select colors and shows
  • Produces 750 lumens with a wide 120-degree beam spread
  • Uses 35 watts and can reduce energy consumption by 80% or more compared with traditional incandescent pool bulbs
  • E26 screw base fits compatible standard pool-light sockets
  • Rated for up to 50,000 hours of operation
  • Designed for 12V pool-light systems only

Blue Square identifies VLB3500-MC as the 12V multicolor version. The similar VLB3501-MC is the 120V model and should not be confused with this bulb.

Quick Product Summary

The Blue Square Vivid 360 VLB3500-MC is a 12V, 35W color-changing LED replacement bulb for compatible swimming-pool light fixtures with an E26 screw socket. It produces 750 lumens through a 120-degree beam and offers seven solid colors plus five light shows controlled through a compatible ON/OFF wall switch. This is a replacement bulb only—not a complete underwater light fixture—so confirm the fixture socket, available housing clearance, voltage, transformer, gasket, and fixture condition before ordering.

Best For

  • Replacing a compatible 12V incandescent pool-light bulb
  • Upgrading an existing pool-light fixture to color-changing LED lighting
  • Compatible fixtures equipped with an E26 screw socket
  • Pool owners who want selectable colors without replacing the complete fixture
  • Existing pool-light systems controlled through a standard ON/OFF switch

Why This Matters

  • Prevents accidentally ordering the similar 120V VLB3501-MC model
  • Allows the existing compatible light housing to be retained
  • Adds selectable colors and programmed shows to the pool
  • Uses less power than a traditional incandescent pool bulb
  • A wide beam spread helps distribute light across the pool
  • Confirming the fixture and gasket condition helps protect the replacement bulb from water intrusion

Common Signs You Need This / Use This When

  • The existing compatible 12V pool-light bulb has failed
  • The current incandescent bulb uses excessive power
  • You want color-changing lighting instead of a single white color
  • The existing fixture is reusable but needs a replacement bulb
  • Your fixture has an E26 socket and sufficient internal clearance
  • A pool professional has confirmed the fixture operates on 12V

Compatibility / Fitment Notes

VLB3500-MC is the 12V version of the Blue Square Vivid 360 multicolor pool bulb. The 120V version is VLB3501-MC. Confirm the label or measured supply voltage before ordering; the two bulbs should not be interchanged.

The bulb uses an E26 screw base and is designed for compatible standard pool-light housings. Compatibility should not be determined by socket style alone. Also verify:

  • Internal fixture clearance
  • Existing fixture and lens condition
  • Correct 12V transformer and electrical supply
  • Fixture gasket or seal requirements
  • Pool-light niche and housing condition
  • Whether the existing fixture is approved for a serviceable replacement bulb

Do not assume compatibility based only on the Pentair, Hayward, Jandy, or another brand name. Match the fixture’s voltage, socket, dimensions, and manufacturer requirements before purchase. Blue Square describes the Vivid 360 bulbs as fitting most E26 bases and standard pool-light housings, but does not claim universal compatibility.

Installation / Use Notes

This bulb should be installed by a qualified pool professional or electrician familiar with underwater pool-light systems. Shut off and verify electrical power before the fixture is removed from the niche. Confirm 12V operation, inspect the housing and lens, and install the correct fixture gasket or seal according to the fixture manufacturer’s instructions.

The bulb is IP64-rated and is not a standalone underwater light. It must remain enclosed inside a compatible, properly sealed pool-light fixture. Improper installation or water intrusion may damage the bulb and are excluded from Blue Square’s published manufacturer warranty.

Once installed, use the compatible ON/OFF toggle switch to move through the seven solid colors and five light shows. Follow the Blue Square color-changing guide and the instructions supplied with the bulb.
