Still Using HPS? Here’s Why It’s Time to Rethink That!

HPS has served its purpose. For years, it was the go-to solution for commercial cultivation, but times have changed. Energy rates have climbed. Margins have tightened. And growers are being asked to do more with less. In that context, running legacy lighting isn’t just inefficient – it’s actively working against your bottom line.

We get it, upgrading can feel like a big move (not to mention a costly one) but sticking with HPS in 2025 means absorbing unnecessary costs, fighting against excess heat, and missing out on the spectrum control that today’s top crops demand. That’s why more cultivators are making the shift to high-performance LED—and seeing real returns for it.

Here’s what you need to know if you’re still on the fence.

HPS

1. When Margins Shrink, Inefficiency Hurts More

HPS systems quietly siphon resources from your operation:

  • Lower photon efficacy (typically 1.7–1.9 µmol/J vs. 2.7+ µmol/J with Aelius LED)
  • Excess energy use, inflating your hydro bills
  • Higher heat output, increasing your HVAC load and operational costs

These inefficiencies may have been tolerable when markets were stronger—but in today’s climate, they compound quickly and choke your profitability.

2. Spectrum Matters More Than You Think

HPS blasts your canopy with orange-heavy light, but lacks the spectrum targeting modern crops need. Aelius LED delivers precision-tuned light spectra that boost key plant processes:

  • Enhanced photosynthetic efficiency
  • Improved morphology and internodal spacing
  • Boosted resin and secondary metabolite production

Our crop-specific tuning means your light isn’t just on—it’s working harder for your yield and quality.

3. Thermal Load = Hidden Operational Risk

Excess heat from HPS doesn’t just tax your HVAC—it creates an unstable grow environment that opens the door to:

  • Disease pressure (powdery mildew, botrytis)
  • Stress events and transpiration swings
  • Reduced quality due to fluctuating VPD

Aelius LEDs drastically reduce thermal output, making it easier to dial in environmental control and protect your crop from preventable stress.

4. ROI Isn’t in the Fixture—It’s in the Output

Many cultivators hesitate to upgrade because they’re already under financial strain. Ironically, not upgrading is what keeps them there.

Here’s what switching to Aelius unlocks:

  • Lower operational costs
  • Improved product consistency and value
  • Fewer disruptions from lighting failures or bulb replacements

Our fixtures are engineered to return value in every grow cycle—and we’ll help you calculate your expected ROI before you spend a dollar.

Break the HPS Cycle

If your lighting hasn’t changed since 2012, your margins probably haven’t either. Aelius LED is built for cultivators who are ready to optimize—not just get by.

We offer:

  • Proven ROI backed by grower data
  • Dedicated support from horticulture pros
  • Tailored retrofits and facility planning
  • Assistance with rebate applications and trial programs

The Bottom Line: HPS Isn’t Just Holding You Back, It’s Dragging You Down

In an industry where every point of efficiency matters, sticking with HPS is like watering your profits with a leaky hose. It’s outdated, underperforming, and costing you more than you think – in energy, crop quality, and peace of mind.

At Aelius LED, we don’t just sell lights—we partner with cultivators to unlock performance they didn’t think was possible. Whether you’re looking to trim costs, stabilize yields, or meet rebate thresholds, we’ve got the tools and the team to help you get there.

Retrofit isn’t a risk – it’s a recovery strategy.

Let’s build a lighting plan that pays for itself and then some.

Connect with our team today and take the first step toward growing smarter.


Because the future isn’t under HPS-it’s under Aelius.
