Product Overview & Applications

The MEGAMAN Metal Halide Bulb (YT-MH) E40 400W (Model: YT-MH/400W/E40-ED) is a high-intensity discharge (HID) lamp designed for heavy-duty commercial and industrial illumination requiring high power output. Operating on a 230V system with a standard E40 cap base, this 400-watt bulb provides intense illumination suited for large spaces, high-bay light fixtures, and floodlight enclosures.

Equipped with a Color Rendering Index (CRI) of ≥90, this metal halide lamp delivers high color fidelity under powerful light output. It is suited for demanding work environments, commercial facilities, and outdoor perimeter floodlighting fixtures designed for tropical monsoon climates when installed within appropriate weather-sealed luminaires.

Key Applications

• Industrial Warehouses & High-Bay Fixtures: Delivers powerful, high-CRI general illumination overhead across expansive factory floors and logistics hubs.

• Outdoor Perimeter & Sports Arena Floodlighting: Fits into external floodlight enclosures to illuminate outdoor parking grounds, construction yards, and sports facilities.

• Commercial Exhibition Halls & Retail Facilities: Provides bright lighting with high color clarity (CRI ≥90) for large display venues requiring accurate color rendering.

Key Features

• High Color Accuracy (CRI ≥90): Delivers color rendering with a CRI rating of ≥90 for applications where accurate visual detail and color rendering are necessary.

• Standard E40 Base Integration: Features an industry-standard E40 mogul screw base for replacement into existing 400W high-intensity discharge luminaires.

• 400W High Output at 230V System Rating: Built for 230V electrical networks, supplying high-wattage HID illumination required across large commercial and industrial sites.

Frequently Asked Questions

Q1: What is the difference between a 400W E40 Metal Halide bulb and lower wattage options like 250W or 150W?

A: The MEGAMAN 400W E40 lamp draws 400W of power to deliver higher intensity lighting compared to lower wattage alternatives, making it suited for higher mounting heights and broader coverage areas.

Q2: Does the MEGAMAN YT-MH/400W/E40-ED bulb feature built-in weatherproofing or monsoon durability?

A: No, the bulb itself does not carry an ingress protection (IP) rating. Weatherproofing and monsoon durability depend entirely on the external IP-rated floodlight or high-bay fixture in which the bulb is installed.

Q3: What transformer, choke, or control gear power setup is required for this 230V bulb?

A: This bulb operates on a 230V power supply and requires a compatible 400W metal halide ballast/choke system and ignitor circuit designed for HID metal halide lamps.

Q4: Is the MEGAMAN YT-MH/400W/E40-ED bulb dimmable or adjustable?

A: Standard metal halide lamps such as this 400W model are non-dimmable and require standard fixed-output control gear to maintain stable arc performance.

Q5: What base type does the MEGAMAN YT-MH/400W/E40-ED model use for installation?

A: It utilizes an E40 screw-in cap base, which allows direct replacement in matching E40 lampholders.

Q6: Why is the CRI rating of ≥90 important for this metal halide lamp?

A: A CRI of ≥90 ensures colors under illumination appear vivid, natural, and true to life compared to lamps with lower color rendering indexes.

Q7: Can this 400W bulb replace standard halogen floodlight bulbs directly?

A: No, metal halide bulbs use an E40 HID socket and specific control gear setup operating at 230V, whereas halogen bulbs use different bases and direct-line wiring.

Q8: Can this bulb be installed in both indoor high-bay and outdoor floodlight fixtures?

A: Yes, provided the target fixture has an E40 lampholder, proper 400W metal halide control gear, and an enclosure rating appropriate for the indoor or outdoor environment.
