LED vs Light Kit: Which Shines Brightest?
Choosing the right lighting for your grow room is crucial. Whether you're a hobbyist or a large-scale grower, understanding the differences between LEDs and traditional HPS lighting can help you make an informed decision. Let’s break it down.
Efficiency
Efficiency plays a huge role in plant growth. While some LEDs outperform HPS lights, not all LEDs are created equal. The higher the efficiency, the more usable light (PAR) your plants receive, rather than wasted heat.
- 600W HPS Light Kit – Around 1.35 μmol/J
- Leading LED Models – Between 2.8 - 3.2 μmol/J
That’s more than double the efficiency in some cases! With LEDs, more energy is converted into plant-usable light, giving you stronger growth without excessive heat output.
Output
PPF (Photosynthetic Photon Flux) measures the total amount of usable light output per second. More PPF means more plant growth potential.
- 600W HPS Light Kit – Around 815 μmol/s
- Leading LED Models – Between 1800 - 2300+ μmol/s
LEDs provide significantly higher light output, delivering intense, even coverage across your grow space—perfect for high-yielding setups.
CO₂ & LEDs: A Game-Changer for Growth
Because LEDs generate less heat than HPS, CO₂ supplementation becomes essential for maintaining rapid plant growth. Adding CO₂ increases photosynthesis, resulting in larger yields, faster growth, and healthier plants.

If you're upgrading to LEDs, don't forget CO₂—it’s the missing piece for maximising your plants’ potential.
Why a DIGI Kit Excels in the Cold
While LEDs are known for efficiency, HPS still holds an advantage in colder climates, where extra heat is needed. A 600W HPS Light Kit provides additional warmth, making it ideal for winter growing.
- Extra Heat for Cold Environments – A 600W HPS bulb generates enough warmth to counteract low temperatures in winter.
- Stable Light Output – Omega digital ballasts regulate voltage, preventing light fluctuations in the cold.
- Dimmable Ballast for Control – Adjust your ballast from 250W to 600W to balance heat and light levels.
- Energy Efficiency – Soft-start technology reduces power surges, helping manage electricity costs in winter.
- Improved Plant Growth – When natural light is weaker, an HPS or MH bulb provides full-spectrum lighting to keep plants thriving.
- Reliable Ignition – Older ballasts struggle in cold temperatures, but Omega’s digital ignition ensures your lights fire up reliably.
For winter growing, a 600W DIGI Kit remains a reliable, high-performing choice—especially if your space needs extra warmth.
