Product Description
The flat GX53 LED bulb is designed for compatible fittings with limited space above the light source. Optonica 1542 is a practical option when you want to keep an existing ceiling or furniture light and replace its bulb. Its round shape and white body follow the compact format used by this type of fitting.
It provides 560 lm of light from 7 W, making brightness straightforward to compare with an existing lamp. The 4500 K neutral white colour temperature suits areas where you prefer lighting without a distinctly warm tone. When using several fittings together, compare their light output as well as colour temperature to avoid unintended differences in brightness.
A 180° beam angle spreads the light across a broad area below the bulb. Depending on where the fitting is installed, this can serve general illumination or a smaller local lighting task. Mounting height and the fitting’s diffuser also affect the result, so consider the complete light rather than the bulb alone when planning its use.
With a 75 mm diameter and 35 mm height, the bulb has clearly defined dimensions for checking clearance. Confirm the socket type, available height and opening size before ordering a replacement. GX53 is a specific connection, so a similar round shape does not by itself establish compatibility. The fitting’s permitted lamp power should also be respected.
Optonica 1542 is not dimmable and is intended for use with a conventional on/off switch. The IP20 rating is suitable for dry indoor locations. If the existing circuit uses a dimmer, select a compatible dimmable bulb instead. Using the same model when replacing several light sources helps keep the lighting consistent throughout the room.
