Specifications

Key Features of the HIB Bulb

✓ 40W Output: Rated at 40W for fittings designed to use this bulb size and power level.

✓ T9 FCL Type: Uses the circular T9 FCL lamp format, so the bulb shape and fitting style must match your existing unit.

✓ Fault Replacement: Ideal when the current bulb flickers, takes time to start, glows dimly, or has stopped working completely.

Why Replace the HIB Circular Bulb

1. Restores Brightness: A fresh lamp can bring back the proper light level when the old bulb has become dull or uneven.

2. Correct Lamp Type: T9 FCL bulbs are shape-specific, so matching the circular format is important for the fitting to accept the replacement.

3. Fixes Flicker Issues: Flickering or delayed start-up is a common sign that the existing bulb is nearing the end of its service life.

4. Matches Power Rating: Using the stated 40W version matters where the fitting is designed around that lamp output and size.
