Due to the various types and appearances of large luminaires, such as LED street lights, floodlights, panel lights, etc., it is difficult to fix the luminaires in a traditional integrating sphere when doing 4π testing. Because there is no test base (platform) to hold so heavy LED outdoor lighting fixtures. LISUN IS-*MA Optical 4π Geometry Ulbrichtsche Kugel With Holder Base is designed for this kind of LED luminaires.

Spezifikation:
• Painting material of integrating spheres is according to CIE-Veröffentlichung Nr. 84 (1989) and IES-LM 79 Standard.
• Internal painting: ρ (λ) ≥0.96 (450nm~800nm) and ρ (λ) ≥0.92 (380nm~450nm)
• Fine diffuse reflection: Reflectance ρ≈0.8 and accuracy of ρ (λ) <1.5%
• Lamp jigs: jigs are for E27, T5/T8/T12 tubes, the holder base is for LED and other luminaires. All samples under test can be installed both up and down directions in the sphere.
- Netzkabel, Stromanschluss und Position der Zusatzlampe sind eingebaut (Zusatzlampe ist optional)
- Netzkabel und Steckdose sind eingebaut. Es ist bequem, die zu prüfende Lampe einzuschalten
- Zwei Fotodetektor Häfen, ein optische Faser port and one temperature sensor port are built-in
• Build-in cross laser can help to install the standard lamp and the lamp under test in the center of the integrating sphere (This item is not included for integrating spheres with a diameter less than or equal to 1 meter)
