Why HATO's 50,000 Hours Outshine Other's 100,000

When you see lighting specs like “50,000 hours” or “100,000 hours,” it’s easy to assume that more means better. But here’s the thing most people don’t realize: lights don’t suddenly switch off—they slowly lose brightness over time. 

So, the real question isn’t just “how long do they last?” 
It’s: how bright do they stay while they’re working? 

Let’s break it down in a way that makes sense, whether you're managing a poultry house, a dairy barn, or a high-tech pig facility. 

What’s the deal with L90B10?

Think of L90B10 as a quality grade for light over time. 

• L90 = 90% of the original brightness is still shining after the stated hours. 

• B10 = only 10% of the lights will fall below that 90% mark. 

That means 90% of your lights will still be delivering 90% of their brightness. 
Pretty impressive, right? It’s a strict and highly reliable standard—and it matters when you depend on consistent light to influence animal behavior, welfare, and productivity. 
 

What do other brands do?

You might see some competitors boasting L70 at 100,000 hours. It looks impressive on paper, but let’s decode it. 

• L70 = the lights are down to 70% of their original brightness. 

• B50 = half of them will be even dimmer than that. 

So yes, it says “100,000 hours,” but the reality? 
Half your lights will be too dim to do their job properly, especially in demanding farm environments where light quality isn’t just about visibility, but animal health and production outcomes.
