Light Efficient Design LED-8030M57 High Bay Retrofit Lamp
This ballast-bypass design targets HID high bay fixtures, delivering broad, even light distribution. It features a rotatable EX39 screw base to direct light where needed, enabling flexible installation in varied ceiling patterns. Reported energy savings can reach up to 80% compared with traditional HID retrofits, making it suitable for large warehouses and manufacturing floors. Its compact form supports retrofit projects with limited space, while maintaining good lumen output for open-area lighting.
120W LED Retrofit Kit – 16,200LM
This kit combines high-lumen output with versatile base options, including E39 and E26 bases, to fit a broad range of fixtures. It delivers up to 16,200 lumens at approximately 135 lm/W with an 80+ CRI rating for accurate color rendering. The design supports mounting flexibility via an adjustable U-bracket for horizontal or vertical installations. It’s aimed at replacing 250-400W HID fixtures, including shoebox and wall-pack applications, and promises substantial energy savings and reduced maintenance needs.
KastLite Open Rated High Bay LED Retrofit Bulb
The KastLite LED retrofit bulb offers a robust 21,200 lumens from a 150W output with a 5,000K color temperature. It features a Mogul EX39 base and is designed for 120-277VAC operation, including 0-10V dimming for greater control. Its 120° beam angle supports open fixtures, and a fanless design reduces noise in quieter industrial spaces while maintaining reliable performance across a wide temperature range. UL-listed for commercial and industrial use, it provides a strong balance of brightness and efficiency.
CyantSolutions 240W LED Retrofit Kit
This 240W retrofit kit is designed to replace 1000W HID/MH fixtures, delivering up to 36,000 lumens at 5,000K. It’s suitable for parking lots, shoebox fixtures, canopies, high bays, and other large-area installations. The kit emphasizes rapid installation with an E39 Mogul base and a 180-degree adjustable mounting bracket, enabling both horizontal and vertical orientation. The result is substantial electricity savings and a broad, uniform light footprint across wide spaces.
dephen 120W UFO LED Light Bulb
The dephen 120W UFO high bay LED bulb uses an E39 Mogul base extender for easy retrofitting in appropriate fixtures, replacing 400W HID lamps. It outputs approximately 18,600 lumens at 155 lm/W and supports motion-sensor compatibility when paired with the appropriate receptacle. Designed for outdoor and indoor high bay environments, it emphasizes energy savings and a compact form factor that fits into space-constrained fixtures. Consider sensor-enabled setups for dynamic space usage and energy management.
Buying Guide: Key Purchase Considerations
- Base compatibility: Confirm your fixture’s base (Mogul E39, E26, or EX39) and whether a ballast bypass is required for longer life and reduced maintenance.
- Voltage and dimming: Ensure the product’s voltage range (often 100-277V) matches your power supply and check if dimming (0-10V) is supported if you need adjustable lighting levels.
- Lumen output and beam angle: Larger spaces benefit from higher lumens and wider beam angles (e.g., 120°) to maximize coverage and minimize dark spots.
- Color temperature and CRI: For warehouse or production environments, 4000-5000K is common; CRI 80+ improves color discrimination for workers and equipment.
- Thermal management and durability: Look for aluminum housings and cooling strategies to sustain lumen maintenance and long lifespans in hot environments.
- Installation considerations: Ballast bypass, mounting brackets, and adjustable bases affect installation time and retrofit complexity.
- Energy savings potential: Compare promised energy reductions (often up to 70-80%) with maintenance savings to estimate total lifetime cost benefits.
- UL/DLC listings: Check UL or DLC certifications for reliability and utility rebates that may apply to your project.
When evaluating options, align lumen output, fixture footprint, and control capability with your space’s dimensions and usage patterns. For projects with multiple fixture heights or ceiling configurations, opt for retrofit bulbs or kits offering adjustable bases, 180-degree mounting flexibility, and dimming where appropriate. Consider sensors or smart controls in dynamic spaces to optimize energy savings further. Always verify ballast bypass requirements and ensure safe, code-compliant installation practices.
