SYLVANIA 20876 18 W 3000 K GX24Q-2 Fluorescent Bulb

18 W GX24Q-2 compact fluorescent

This 18 watt triple-tube bulb uses a GX24Q-2 base and produces 1200 lumens at a 3000K colour temperature. It is designed for general indoor lighting in fixtures that accept this pin configuration. The 82 CRI rating provides acceptable colour rendering for everyday tasks. Shoppers needing higher output or a different base type should look elsewhere.

Interface and dimming limits

The GX24Q-2 base only works with matching electronic ballasts; it cannot be used in screw-in sockets or magnetic ballast fixtures. This model is not dimmable, so it must be paired with a non-dimming ballast or switched circuit. Buyers who require dimming or a different base standard will need another product.

Installation notes

Insert the four pins straight into the socket until the bulb seats firmly; forcing it at an angle can bend the pins. The triple-tube shape is wider than a single-tube lamp, so confirm the fixture housing has enough clearance before purchase. Glass is fragile — handle by the base, not the tubes, to avoid breakage.
