The NLS 10123 is a 9W LED tubular lamp with an E27 screw cap and selectable colour temperature, rated 720 lumens. A toggle switch on the side of the 10123 selects 3000K warm white, 4000K cool white, or 6400K daylight. The lamp measures 37mm in diameter and 115mm in length, spreads output across a 180 degree beam angle, and is not dimmable.
Pendant and decorative fittings frequently carry a narrow shade that a standard round globe fouls before it seats. Replacing the fitting to accommodate the globe costs considerably more than the original lamp did. The 10123 measures 37mm across the tubular body and 115mm in overall length, so it seats in shade openings that will not accept a wider profile.
A lamp that physically fits is only half the specification, because the colour temperature still has to suit the room. The 10123 carries 3000K, 4000K, and 6400K on a toggle switch positioned on the lamp body. A pendant above a dining table and one in a laundry take an identical part number at different configurations. The E27 screw cap lands directly in standard Edison screw lampholders.
The 10123 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 an E27 screw cap and does not fit bayonet lampholders.
(10123)
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 10123 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 an Edison screw cap is required, the SAL LT409TC-E27D is an alternative.
The lamp measures 37mm in diameter and 115mm in overall length. The narrow 37mm body suits shades and fittings that will not take the wider profile of a round globe. Confirm the fitting allows 115mm of clearance before purchase.
An E27 screw cap fits standard Edison screw lampholders, including pendant fittings, batten holders, and table lamps. The T37 tubular format measures 37mm across, so it suits shades that will not seat the wider profile of a round globe. It does not fit bayonet lampholders.
The 10123 is a replacement lamp and screws into a standard E27 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.
