SAL LT Series LT409TC LED Tubular Lamp 9W B22 - Dimmable Selectable CCT

Description

Dimmable. Three colours. Drop-in CFL replacement for dimming circuits.

The SAL LT Series LT409TC/B22D is a 9W dimmable LED tubular lamp with selectable colour temperature (3000K / 4000K / 6000K) and a B22 bayonet cap base — the dimmable variant of the LT409TC, with an integral trailing-edge LED driver that works seamlessly with most modern Australian LED-rated wall dimmers. A direct retrofit for existing B22 CFL and incandescent bayonet fittings on dimming circuits, it delivers smooth, quiet trailing-edge dimming with no rewiring or fixture replacement required.

Trailing-Edge Dimming — Smooth, Silent, and Compatible With Modern Australian Dimmers

The LT409TC/B22D's integral trailing-edge dimmable driver is the key difference from the standard LT409TC/B22. Trailing-edge dimming is the technology used in virtually all modern Australian LED wall dimmers — Clipsal Iconic Dimmable, HPM, Mercator, Legrand — and it delivers smooth, flicker-reduced brightness control with minimal audible buzz from either the lamp or the dimmer. CFLs typically can't dim well or at all, and older leading-edge incandescent dimmers cause flicker and buzzing when used with LED lamps. The LT409TC/B22D solves both: it replaces a non-dimmable CFL or incandescent and adds genuine trailing-edge dimming capability in the same socket, with no rewiring. The result is comfortable, mood-controllable lighting for dining rooms, bedrooms, living rooms, and hospitality spaces — from a single lamp swap.

Three colour temperatures — commit on site with the power off.

The on-lamp CCT switch gives three options before installation: 3000K Warm White — the most popular CCT for residential dimming applications, suited to dining rooms, living areas, bedrooms, and table lamps where a warm, traditional-incandescent feel is the goal; 4000K Cool White for kitchens, bathrooms, hallways, laundries, and home offices; and 6000K Daylight for garages, workshops, walk-in robes, and task areas where maximum visibility matters. Always set the CCT with the supply switched off — changing the setting under live power may damage the driver.

LT409TC/B22D vs LT409TC/B22 — choosing the right variant.

Both are SAL LT Series 9W selectable-CCT B22 tubular lamps with the same light output, CRI, beam angle, and dimensions. The LT409TC/B22 is non-dimmable — use it on standard switched circuits without a dimmer. The LT409TC/B22D (this product) has an integral trailing-edge dimmable driver — use it on circuits with a compatible LED-rated trailing-edge wall dimmer. The "D" suffix indicates Dimmable. Choose based on whether your circuit has a dimmer.

Q: What dimmer should I use with the LT409TC/B22D?
A: A trailing-edge LED-rated wall dimmer. Most modern Australian dimmer ranges include trailing-edge LED-compatible models, including Clipsal Iconic Dimmable, HPM, Mercator, and Legrand. Avoid older leading-edge dimmers designed for incandescent and halogen — these may cause flicker, buzzing, or refusal to dim. Check the dimmer's minimum and maximum LED load rating and avoid mixing dimmer brands on the same circuit.

Q: Will the LT409TC/B22D fit my existing CFL fitting?
A: If your fitting has a B22 bayonet base (two opposing pins that twist into the socket), yes. The lamp's 40mm diameter and 105mm length is similar to a typical CFL spiral and fits most lampshades, pendants, and open-shaded fittings on dimming circuits. For very compact or shallow fittings, measure the available internal height before ordering.

Q: Why might the lamp flicker or buzz when dimmed?
A: The most common cause is dimmer incompatibility. Check that your wall dimmer is a trailing-edge LED-rated type, not a leading-edge incandescent dimmer. Also check that the dimmer's minimum LED load is met — some dimmers require a minimum of 10W or more, and a single 9W lamp may fall below the threshold. If issues persist, upgrading to a modern trailing-edge LED-rated dimmer will typically resolve them.
