| Lamp Power | 20–100 W for common corn-bulb models | Supports applications ranging from residential lighting to commercial and industrial spaces. | Select wattage according to the required lumen output and fixture rating. |
| Luminous Efficacy | Approximately 80–150 lm/W, depending on LED design and driver | Provides more light per watt than many traditional incandescent and HID lamps. | Compare tested lumens and input watts rather than relying on wattage alone. |
| Color Temperature | 2700 K, 3000 K, 4000 K, 5000 K, or 6500 K | Offers warm, neutral, and daylight appearances for different environments. | Warm white suits hospitality and homes; daylight is common in warehouses and outdoor areas. |
| Color Rendering Index | CRI ≥80 is common; CRI ≥90 is available for color-sensitive applications | Improves the natural appearance of objects and surfaces. | Use CRI ≥90 for retail, display, artwork, and inspection areas. |
| Input Voltage | Commonly AC 85–265 V or AC 100–277 V, depending on the model | Allows use across many residential, commercial, and industrial electrical systems. | Confirm the rated voltage before installation, especially for 277 V circuits. |
| Power Factor | Typically ≥0.90 on commercial-grade models | Reduces reactive power demand and helps improve electrical efficiency. | Check the driver datasheet for the actual power-factor value. |
| Base Compatibility | E26/E27, E39/E40, and other bases may be available | Enables retrofit use in many existing sockets and fixtures. | Match both the base size and the fixture’s maximum permitted wattage. |
| Rated Lifetime | Approximately 25,000–50,000 hours under suitable operating conditions | Reduces replacement frequency and maintenance labor. | Review the published L70 rating, warranty terms, and operating temperature. |
| Heat Management | Aluminum heat sink with ventilated corn-style housing | Helps dissipate heat and maintain LED and driver performance. | Avoid enclosed fixtures unless the product is specifically rated for enclosure use. |
| Ingress Protection | IP20 for dry indoor versions; IP65-rated versions are available for suitable outdoor use | Provides options for indoor, damp, dusty, or semi-outdoor environments. | An IP rating does not replace the need for a weatherproof fixture where required. |
| Dimming | Non-dimmable is common; compatible dimmable versions may be offered | Allows energy and light-level control when the driver and dimmer are compatible. | Verify dimmer type, minimum load, and flicker performance before installation. |
| Operating Temperature | Commonly about −20°C to 45°C ambient temperature | Supports use in a broad range of indoor and outdoor climates. | Check the product label for the exact temperature range and cold-start behavior. |
| Safety and Compliance | Look for applicable certifications such as CE, RoHS, UL, or DLC, depending on the destination market | Helps demonstrate electrical safety, restricted-substance compliance, and market eligibility. | Confirm certification numbers and test reports with the seller or testing body. |
