When it comes to keeping your animals comfortable and your greenhouse frost-free, not just any heat lamp will do. You need something tough, dependable, and ready to handle daily agricultural demands. That’s where the DURABulb™ Heat Lamp from QC Supply shines...literally.

We’ve all been there: heat lamps that crack, fizzle out too soon, or don’t hold up to barn conditions. The DURABulb is different. It's QC Supply's proprietary solution designed for the ag world... built to perform in swine and poultry barns, greenhouses, and beyond. 

A lot of heat lamps on the market are mass-produced with lightweight glass and flimsy bases. That might work in a garage or for temporary use, but agricultural customers need more.

DURABulb lamps are made with heavy-duty glass and a durable brass base. That matters when you're dealing with high humidity, dust, and demanding work environments. Whether you're using them in a farrowing barn, brooder house, or frost-prone greenhouse , these bulbs are made to stand up to daily use.

They’re available in both 125W and 175W models , so you can choose the output that makes the most sense for your setup. The PAR38 design delivers focused radiant heat where it's needed most, helping you warm specific zones efficiently without wasting energy.

Not sure which model to choose? Here's a quick breakdown:

• 125W is a great option for smaller enclosures, brooders, or pens where space is limited and you want a gentler heat output .
• 175W is ideal for larger pens, open barn areas, or colder environments where a stronger heat source is needed.

Many operations find it helpful to keep both on hand , allowing for flexibility across different seasons or stages of animal development. 

• Swine operations: Keep newborn piglets warm in farrowing crates without worrying about overheating or bulb failure.
• Poultry barns: Provide targeted warmth during brooding that can make all the difference in early-stage chick development.
• Greenhouses: While not a grow light, the DURABulb helps maintain temperature-sensitive areas and reduces the risk of cold stress in delicate plants or seedlings.

Small animal setups: These bulbs can also be used for dogs, cats, or other small animals that need consistent warmth in outdoor kennels or barns.

Wherever you need heat, the DURABulb brings consistency and reliability to the job.

DURABulb™ heat lamps were independently tested and confirmed to emit peak infrared radiation around 1030nm, placing them squarely in the IR-C range for effective agricultural heating.

Independently tested to produce infrared output around 1030nm, making it ideal for targeted agricultural heating applications 

PAR38 refers to a Parabolic Aluminized Reflector bulb that is 4.75 inches in diameter. This design focuses energy in a concentrated beam , and in the case of DURABulb, it delivers verified infrared heat output.

At QC Supply , we know our core customers...you want products that work hard, last longer, and deliver true value. The DURABulb™ was developed with that mindset. It may look like just another heat lamp, but when you hold it, the difference is clear.

It’s sturdy. It feels solid. And most importantly, it performs.

DURABulb lamps ship individually and in cases of 12, so you can stock up easily when you're running multiple pens, rooms, or zones.

Even the best heat lamp won’t deliver results if it’s not used properly. To get the most out of your DURABulb, keep these best practices in mind:

• Mount securely: Use fixtures designed for agricultural use and make sure they’re tightly fastened. Loose or unstable fixtures are a common cause of accidents.

• Mind the distance: Always maintain proper spacing between the lamp and animals, bedding, or plants. Too close can cause overheating or fire risks; too far and you lose effectiveness.

• Inspect regularly: Agricultural environments are tough. Check your bulbs and cords routinely for wear, moisture exposure, or buildup of dust and debris.

• Avoid moisture contact: While DURABulb lamps are built tough, direct contact with water or heavy condensation can damage components or cause electrical hazards. Use in protected or covered areas only.

• Use with a guard or reflector when needed: Guards can help protect the bulb from being knocked loose or broken, especially in pens or active areas.

• Monitor temperature zones: A simple thermometer can help ensure you're hitting your target temps without overheating. Animals and plants thrive best with consistent warmth—not extreme highs.

When you invest in quality heat lamps like the DURABulb, a little extra care goes a long way in maximizing both safety and performance.
