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 Sphère intégratrice With Holder Base is designed for this kind of LED luminaires.

Spécification:
• Painting material of integrating spheres is according to CIE Pub.No.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.
- Le câble d'alimentation, la borne d'alimentation et la position de la lampe auxiliaire sont intégrés (la lampe auxiliaire est en option).
- Le câble d'alimentation et la prise sont intégrés. Il est pratique d'allumer la lampe testée.
- Deux détecteur photo ports, un fibre optique 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)
