AlphaFit Duo LED Bulb – Dual-Color Watermelon Light Bulb (Gen 2) | Red/Purple

Dual-color AlphaFit Gen 2 LED bulb engineered for glass watermelon light housings. Uses independent LED banks and a compact emission surface to produce a uniform star-beam pattern with no center void across both colors.

---

True Dual-Color LED Control System

Three-wire configuration provides independent control of each color without switchback behavior.

Features include:

• Dedicated LED bank per color (Red / Purple)
• Full-power operation on each circuit
• Secondary circuit overrides when both are powered

Supports clean integration with marker, brake/turn, or auxiliary circuits.

---

23W High-Output Gen 2 Platform

Each color operates at full output independently.

Specifications:

• 23W per active color
• Stable intensity with no brightness-based switching
• Consistent output across both color channels

Machine-built Gen 2 platform improves reliability and output consistency.

---

Dual LED Chip Bank Architecture

Each side of the bulb contains:

• One dedicated LED bank for Red
• One dedicated LED bank for Purple

Benefits include:

• Instant color switching
• No color blending or bleed
• Identical beam pattern for both colors

Maintains consistent optical performance regardless of active color.

---

Focused Optical Output for Glass Lenses

Designed specifically for glass star-pattern watermelon lenses.

Key characteristics:

• Compact emission surface for precise optical control
• Full beam fill with no center dark spot
• Optimized for radial prism (starburst) lenses

Outperforms multi-diode and dual-revolution bulbs in glass applications.

---

Advanced Thermal Management System

Hybrid cooling system supports continuous operation.

Cooling components include:

• Oversized anodized aluminum housing
• Internal active cooling fan
• Passive heat sink beneath LED chips

Maintains thermal stability under sustained load conditions.

---

Positive-Pressure Venting System

Active airflow manages internal moisture.

Features include:

• Positive-pressure airflow within housing
• Condensation reduction during operation
• Moisture expelled through internal circulation

Improves durability in varying environmental conditions.
