Description
Description
Ushio Hilux Opti-Red High Pressure Sodium Bulb is a grow light bulb for horticulture lighting, built to deliver a flowering-focused spectrum with purposeful blue support for efficient vegetative growth. This HID grow lamp is made for indoor gardens and controlled environments where consistent light output and repeatable results matter.

This bulb is part of a super high output lamp technology platform, designed around an optimized spectrum and a refined distribution pattern to help deliver even canopy coverage. The Opti-Red lamp emphasizes maximized output in both the red and blue spectral range, giving you a strong flowering-forward profile while still keeping blue light present for sturdy, well-structured plant growth. That balance is a key reason growers choose this style of HPS grow lighting when they want a single lamp approach that supports both vegetative growth efficiency and flowering performance.

Output stability is a major buying factor in HID lighting, and this bulb is engineered for reliable operation throughout the growth cycle with a focus on highest quality and consistent performance. When you’re replacing a tired lamp or standardizing a room with matching bulbs, that steady performance helps keep growth more uniform across benches and zones. The tubular, low profile design is also intended for compact fixtures, supporting cleaner layouts in tighter grow areas where equipment spacing matters.

This bulb is suited to a wide set of horticulture lighting applications, including greenhouse lighting, hydroponics, aquaponics, microgreen lighting, and controlled environment agriculture. It’s a good fit for growers who want an Opti-Red high pressure sodium grow light bulb with an optimized spectrum, strong red-and-blue spectral output, and consistent performance from cycle to cycle, especially when flowering-focused lighting is the priority.

Warnings & Safety
Light & Eye Safety

Do not stare directly into operating grow lights, HID bulbs, LEDs, or high-intensity lamps. Bright light may cause eye discomfort or strain. Use appropriate eye protection when working near intense lighting and turn lights off when servicing when possible.

Bulb & Lamp Handling

Use only compatible bulbs or lamps approved for the fixture, ballast, and wattage. Allow bulbs and fixtures to cool before handling. Do not touch hot bulbs, damaged bulbs, or exposed sockets. Replace cracked, damaged, flickering, or expired lamps as directed by the manufacturer.

Label & Manufacturer Directions

Always follow the official product label, package directions, and manufacturer safety information. Check the manufacturer website or official product documentation for the most complete and current usage, safety, storage, and disposal details. This notice is general guidance and does not replace the product label.

Mercury Lamp Disposal

Some HID lamps, including certain metal halide, ceramic metal halide, and high pressure sodium lamps, may contain mercury or require special disposal. Do not place broken or mercury-containing lamps in regular waste unless permitted locally. Follow the product label, manufacturer instructions, and local disposal rules.

Lamp Installation Safety

Turn off power and allow the fixture and lamp to cool before installing, removing, or replacing the lamp. Use only lamps that match the fixture, ballast, socket, wattage, and manufacturer specifications. Do not force the lamp into the socket.

Hot Bulb & Breakage Safety

Lamps may become very hot during use. Do not touch hot lamps or place them near flammable materials. Handle carefully to avoid breakage. If a lamp is cracked, broken, discoloured, flickering, or damaged, stop use and replace it according to the manufacturer instructions.
