There are several types of LED bulbs, each designed to meet specific lighting needs. Understanding the different types helps in selecting the most appropriate bulb for each use case. Use these fixture and application details when choosing bulbs:


Selecting the right LED bulb involves considering several factors to ensure reliable performance and efficiency. Here are the key factors to consider:

LED light bulbs are available in a wide range of form factors to fit virtually any fixture. Understanding the differences helps you select the right bulb for your application:
| Bulb Type | Base | Common Wattage | Best For |
|---|---|---|---|
| LED Corn Bulbs | E26 / E39 | 20-150W | Post-top, wall packs, area lights |
| LED T8 Tubes | G13 bi-pin | 12-22W | Troffers, strip fixtures, garages |
| LED A-Shape | E26 | 5-15W | General purpose, residential |
| LED PAR / BR | E26 | 8-20W | Recessed cans, track lighting |
| LED HID Replacement | EX39 / E39 | 35-300W | Shoebox, wall packs, high bays |
When comparing LED bulbs, check the product listing for UL or ETL listing, warranty term, base type, voltage, enclosure rating, and dimming compatibility. Browse LED corn bulbs, T8 tubes, and specialty lamps above, then confirm the exact specification before ordering.
LED light bulbs are a modern lighting solution that offers numerous advantages over traditional bulbs. Below, we've answered a few common questions concerning this highly efficient light source:
LED light bulbs use light-emitting diodes to produce light instead of a heated filament. Compared with incandescent lamps, they use less electricity, produce less waste heat, and last longer. For commercial retrofits, the important checks are base type, voltage, fixture size, heat management, and whether the old ballast must be bypassed.
LED corn bulbs use rows of LED chips around a cylindrical lamp body, which gives the bulb its corn-like shape. They are used for higher-output retrofits in warehouses, factories, parking lot fixtures, post tops, wall packs, and street lights. Many replace metal halide, mercury vapor, or high-pressure sodium lamps after the ballast is removed or bypassed. Check base type, fixture size, voltage, enclosure rating, and heat clearance before using a corn bulb instead of a full fixture replacement.
Yes, many LED bulbs can be installed outdoors and are able to withstand various weather conditions. It's important to choose LEDs with an IP Rating for outdoor use – such as IP65. This ensures they can handle exposure to moisture, temperature fluctuations, and other environmental factors. Outdoor LED fixtures are used in street lighting, high-powered parking lot lights, spot lights and expansive landscape lighting.
Not all LED bulbs are compatible with dimmer switches. It's important to choose LED bulbs specifically designed for dimming if you plan to use them with a dimmer switch. Additionally, a compatible dimmer switch designed for LED bulbs is required to avoid issues such as flickering or reduced bulb lifespan. Always check the specifications of the LED bulb and the dimmer switch to ensure compatibility.
A 100-150W LED corn bulb typically replaces a 400W metal halide lamp while delivering equal or greater lumen output. LED corn bulbs fit directly into E39 mogul base sockets found in wall packs, post-top fixtures, and shoebox lights, making them a straightforward retrofit without fixture replacement.
Most commercial-grade LED light bulbs are rated for 50,000 to 100,000 hours of operation. At 12 hours of daily use, a 50,000-hour LED bulb lasts approximately 11 years before needing replacement, a much longer service life than the 2,000-hour lifespan of incandescent bulbs or the 10,000-20,000 hours typical of fluorescent and HID lamps.
Color temperature depends on the application. Commercial and industrial spaces typically use 4000K (neutral white) or 5000K (daylight) for maximum visibility and alertness. Retail and hospitality environments often prefer 3000K (warm white) for a more inviting ambiance. Tunable LED light bulbs that switch between color temperatures provide flexibility for multi-use spaces.
Choose LED bulbs by base type, wattage, voltage, color temperature, enclosure rating, and retrofit requirements. If the fixture is commercial, outdoors, enclosed, or tied to an old ballast, contact LED Light Expert before ordering so the bulb matches the application.
