The most cost-effective way to buy the Ossila LED Solar Simulator Lamp. By offering the Ossila LED Solar Simulator Lamp individually, we can provide the same technical features at a much lower price. This is ideal if you would like to add a solar simulator to your existing set up and have no need for the additional hardware that comes with the full product package.
Identical to the LED solar simulator head sold with the adjustable height z-stage or Solar Cell I-V System, the stand-alone solar simulator lamp unit is class AAA over a 15 mm diameter circular area (using the latest IEC 60904-9:2020 International Standard). The lamp is suitable for use over larger areas too, with a class B spatial non-uniformity rating for areas up to 25 mm in diameter and a class C rating for diameters up to 32 mm.
LED solar simulators offer several advantages over arc lamp solar simulators. They are cheap to run thanks to the high efficiency of LED lights and require zero maintenance. Arc lamps, by comparison, waste a considerable amount of energy as heat and need at least 30 minutes to warm up. The Ossila LED Solar Simulator Lamp is ready to use just a few minutes after you first turn it on.

Why Should You Buy the Ossila LED Solar Simulator Lamp?
The Ossila LED Solar Simulator Lamp offers great value and excellent quality. To achieve this, we use an array of powerful LEDs to accurately simulate the AM1.5G spectrum over a wavelength of 350 – 1050 nm. Furthermore, through our free, downloadable software, you have the ability to control the intensity of each individual LED. This gives you maximum control over the output of your Solar Simulator Lamp.

Spectral Irradiance Graphs
The programmed spectral irradiance of the Ossila LED Solar Simulator Lamp is shown in the graph above. The Ossila light source is initially calibrated so that it emits a total integrated power of 100 mW/cm2 (1 Sun) over the wavelength range 350 nm – 1000 nm. The Ossila LED Solar Simulator Lamp achieves a Class A rating for each wavelength range defined by solar simulator standard guidelines. This calibrated Class AAA spectrum is emitted only a few seconds after powering up.
The Ossila LED Solar Simulator Lamp also allows you to adapt the output spectrum of your lamp as you desire. The above graph shows a spectral distribution at 0.7 Suns to demonstrate AM1.5G spectral match more clearly to the AM1.5G spectrum. Whether you value spectral match or total power irradiance, the Ossila LED Solar Simulator Lamp can adapt to meet your needs. For more information on how we present our solar simulator spectral data here, read our guide on interpreting spectral irradiance graphs.
Spectral Irradiance
The spectral match classification measured how well a solar simulator replicates the solar spectrum in terms of wavelength distribution. At 1 Sun irradiance at 8.5 cm, the Ossila LED Solar Simulator Lamp acheives Class A output in all wavelegnth catagories. At this irradiance, the Ossila LED Solar Simulator Lamp achieves a Class A classification for spectral irradiance.
Spatial Uniformity
Solar simulators aim to distribute light uniformly across a sample, replicating sunlight. The spatial uniformity rating gives a measure of how uniform a solar simulator's distribution is.
At the working distance of 8.5 cm and output power of 1 sun, the Ossila LED Solar Simulator Lamp achieves a spatial non-uniformity class A rating over a 15 mm diameter, making it ideal for testing small area devices. It also achieves a class B rating over 25 mm diameter, and a class C rating at 32 mm diameter, so you also can test larger cells with the Ossila LED solar simulator Lamp with ABA or ACA classification.
Temporal instability
The temporal instability classification measures the output consistency of a solar simulator.
The temporal instability graph proves that the light output from the solar simulator is stable over a long time frame, so it achieves a Class A Temporal Instability classification. This means you can conduct long-term experiments with the Ossila LED Solar Simulator Lamp without worrying about spectral fluctuation. This includes measurement such as solar cell lifetime measurements or experiments to measure light degradation effects.
Mounting information
The solar simulator lamp comes with a permanent mounting bracket attached to the rear. This can be used to afix the lamp to a custom gantry. The dimensions and spacing of the mounting holes are shown below. All holes are unthreaded.
LED Solar Simulator Lamp Features
LED Lamp
The Ossila Solar Simulator uses light-emitting diodes to generate its light output. The advantages of LEDs over arc-lamp or incandescent alternatives include:
- High efficiency
- Long operating lifetime
- High temporal stability
- Zero maintenance
- Spectral tunability
- Virtually zero warm-up time
- Ozone-free
- No explosion risk
These many advantages of LED light sources result in a solar simulator that can reliably and accurately reproduce the solar spectrum.
Easy-to-Use Software
There is no special programming or set up needed for the Ossila Solar Simulator to deliver dependable, high-quality solar irradiance. In most cases, all you need to do is plug it in and turn it on. By default, the lamp will deliver a calibrated output optimized to meet the solar spectrum.
However, our free, downloadable software allows you to control the LED outputs individually as well as change the total irradiance output. You can also control the lamp using a serial command library. This can be useful for specialist measurements or non-conventional spectral output (e.g. indoor PV measurement, low light intensity conditions, etc).

The Solar Spectrum
The purpose of a solar simulator is to recreate the sunlight received on Earth. This is easier said than done as sunlight starts its journey in complex nuclear reactions in the sun's core, and is modified on it's journey to us through interactions with the Earth's atmosphere.
