As stated in the title, we install OSRAM LEDs from the Duris series in ESTA LED strips and products, depending on the purpose of the product.

OSRAM is a renowned European lighting manufacturer and its LED light sources are among the highest quality, most durable and energy-efficient products in the world. This can be further seen from the features and attached downloads.

Features
– Packaging: white SMT package, colored diffuse silicone resin
-Type. Radiation: 120° (lambert emitter)
– Color Temperature: 2200K – 6500K
– CRI: 80 (min.), 85 (typ.), R9: 0 (min.)
– Lumen maintenance: Test results available according to IESNA LM-80
– ESD: 2 kV towards. according to ANSI/ESDA/JEDEC JS-001 (HBM, Class 2)
– Luminous flux: typ.: 29.2 lm @ 4000 K
– Luminous efficacy: Typ.: 165 lm/W @ 4000 K

You can see that these LEDs have 165 lumens per watt which puts them in energy class C.

If you are interested and look at the products offered on the market, you will see that it is very rare to find a product with such a feature. If they are declared, they are usually in class F and G, or more simply, they produce 80-90 lumens per W maximum. So you need almost twice as much energy to get the same brightness.

The mantra that is often mentioned is that LED lighting saves energy many times over compared to the old technology, which is true, but the part where there are big differences from the manufacturer is not added.
