Product Overview

Image Description: An image showing the Frost 300W PS35 Mogul Base Frosted Light Bulb. The bulb has a pear shape (PS35) with a frosted glass finish, which diffuses light for a softer glow. The base is a brass-colored mogul (E39) screw-in type, designed for larger fixtures. The overall appearance is that of a traditional incandescent light bulb.
The Frost 300W PS35 light bulb is a high-wattage incandescent lamp with a frosted glass finish and a Mogul (E39) base. It is engineered for extended operational life, up to 14,000 hours, making it suitable for environments requiring reduced maintenance. Its construction includes a rugged 5-filament support, pure tungsten coil, reflector disc, and a durable brass base.
Setup and Installation
- Safety First: Before attempting to install or replace the light bulb, ensure the power to the fixture is turned off at the circuit breaker or fuse box. Allow any previously used bulb to cool down completely before handling.
- Check Compatibility: Verify that your lighting fixture is designed to accept a 300-watt incandescent bulb and has a Mogul (E39) base. Ensure the fixture's voltage rating matches the bulb's 130 Volts.
- Unpack the Bulb: Carefully remove the new bulb from its packaging, holding it by the glass portion or the base, avoiding direct contact with the filament if visible.
- Screw in the Bulb: Gently screw the bulb into the E39 Mogul base socket in a clockwise direction until it is snug. Do not overtighten, as this can damage the bulb or the fixture.
- Restore Power: Once the bulb is securely installed, restore power to the fixture from the circuit breaker or fuse box.
- Test Operation: Turn on the light switch to confirm the bulb is functioning correctly.
Important: This bulb operates at 130 Volts. Using it in a 120 Volt system will slightly reduce its brightness and wattage but can extend its lifespan. Using it in a system with higher voltage than 130V is not recommended and can significantly shorten its life or cause failure.
Operating Instructions
Operating the Frost 300W PS35 light bulb is straightforward once installed. Simply use the standard wall switch or fixture control to turn the light on or off.
- Power On/Off: Activate the light by flipping the connected switch to the "ON" position. Deactivate by flipping the switch to the "OFF" position.
- Dimmable Feature: This bulb is dimmable. If your fixture is connected to a compatible dimmer switch, you can adjust the light intensity by manipulating the dimmer control. Ensure your dimmer switch is rated for incandescent loads and can handle the 300-watt capacity of this bulb.
Maintenance
Proper maintenance can help ensure the longevity and optimal performance of your light bulb.
- Cleaning: Before cleaning, always turn off the power to the fixture and allow the bulb to cool. Gently wipe the frosted glass with a soft, dry, lint-free cloth. Do not use liquid cleaners or abrasive materials, as these can damage the bulb's finish or internal components.
- Replacement: This bulb has an average rated life of 14,000 hours. In commercial applications, it is engineered to last approximately 18 months of continuous use. Replace the bulb when it reaches the end of its operational life or if it fails prematurely.
- Disposal: Dispose of old incandescent bulbs according to local regulations. While they do not contain mercury like some other bulb types, proper disposal is always recommended.
