A unique LED lighting
Technology keeps advancing, and LED High Bay Light PRIMUS is the proof. Without exaggeration, this lighting fixture is a unique element in our market – A winner in the category of “Energy Efficiency”.
We first saw the fixture by the end of 2022. We were curious – We hadn’t seen LED lighting with such high energy efficiency on the market before. We sent it to the lab to verify the parameters. The tests confirmed PRIMUS’ huge energy efficiency compared to competing LED fixtures.
Highly energy efficient – What does that mean?
Energy efficiency tells us how many lumens per watt the lighting emits.
Energy efficiency = light flux/electric power
In layman’s terms – it tells us the energy savings on the fixture. It means “netto power” – with all losses (both optical and electrical) accounted for. To give you an idea = A traditional incandescent bulb has an efficiency of about 10-15 lm/W, a common fluorescent light of about 40-60 lm/W and LED lighting of about 100-170 lm/W.
PRIMUS has an extraordinarily high energy efficiency – up to 197 lm/W (at 4,000 K and colour rendering index (CRI/Ra) > 80). The following chart shows average values for the tested PRIMUS fixture.
| Measured values | |||
| Light flux | 28,575 lm | 22,820 lm | 16,930 lm |
| Input | 150 W | 118 W | 86 W |
| Energy efficiency | 190.5 lm/W | 193.4 lm/W | 196.9 lm/W |

Comparison to common lighting solutions
We compared PRIMUS with other – commonly used – lighting solutions: a discharge lamp, an economy-grade LED light and PRIMUS. As you can see, PRIMUS can provide even higher savings than a common LED light.
| Discharge lamp (old-fashioned lighting solution) | Economy-grade LED light (standard lighting solution) | LED High Bay Light PRIMUS (new lighting solution) | |
| Input | 400 W | 200 W | 150 W |
| Annual consumption (16 hr/day, 260 days/year, 30 EUR/MWh) | 562 EUR | 250 EUR | 187 EUR |
| Savings | - | 56% | 67% |
| - | 312 EUR | 374 EUR |
Other advantages of PRIMUS
Besides the high energy efficiency, PRIMUS offers additional pros:
- resistance – suitable for challenging environments (production sites, workshops, storage rooms...)
- long operation time – up to 131,000 hours for the L70B50 variant (at 70% of light flux) and 70,000 hours for the L80B50 variant (at 80% of light flux)
- extended 5 years warranty
- control options (0-10V, HF sensor and PIR, DALI, DALI 2)
- different optic systems for optimal beaming angles
- most common types on stock
