The NLS 10122 is a 9W LED tubular lamp with a B22 bayonet cap and selectable colour temperature, rated 720 lumens. A toggle switch on the side of the 10122 selects 3000K warm white, 4000K cool white, or 6400K daylight. The lamp uses a T37 tubular body, spreads light across a 180 degree beam angle, and is not dimmable.
Colour temperature is the one specification a sparky cannot finalise from the van. A customer wants warm white throughout the bedrooms and daylight in the laundry, and fixed-colour lamps mean carrying three separate part numbers to cover a single residential property. The 10122 accommodates 3000K, 4000K, and 6400K in one lamp, selected by a toggle switch positioned on the side of the body.
One tubular lamp on the van replaces three. The 10122 delivers warm white, cool white, and daylight from a single part number, so a replacement on a callout no longer depends on predicting the colour temperature before leaving the workshop. The toggle sits on the lamp itself, so the configuration changes without a controller, a dimmer, or an alternative fitting. The B22 bayonet cap lands directly in standard bayonet lampholders.
The 10122 is not dimmable and should not be installed on a dimmer-controlled circuit. The colour toggle sits on the lamp body, so the lamp must stay accessible for the setting to be changed after installation. It carries a B22 bayonet cap and does not fit E27 screw lampholders.
(10122)
A toggle switch on the side of the lamp body selects 3000K warm white, 4000K cool white, or 6400K daylight. The selection is made at the lamp rather than through a controller or a wall dimmer, and can be changed after installation while the lamp remains accessible.
The 10122 is not dimmable and is not suitable for dimmer-controlled circuits. Colour selection is handled by the toggle switch on the lamp body, not by a dimmer. Where a dimmable tri-colour lamp in a bayonet cap is required, the SAL LT409TC-B22D is an alternative.
A B22 bayonet cap fits standard bayonet lampholders, including batten holders and pendant fittings. The T37 tubular format is narrower than a standard round globe, so it suits shades and fittings that will not seat a GLS profile. It does not fit E27 screw lampholders.
The 10122 is a replacement lamp and fits a standard B22 bayonet lampholder by hand, so no electrician is needed. Switch the light off at the wall before fitting it. Work on the lampholder, the fitting, or the wiring behind it is licensed electrical work.
3000K warm white suits bedrooms and living areas. 4000K cool white suits kitchens, bathrooms, and general work areas. 6400K daylight suits garages, workshops, and laundries. All three settings sit on the one lamp, so the colour can be matched to the room after the lamp is fitted.
