Lighting — FAQ
What CRI rating do photographers need in LED strips?
Demand CRI 95 minimum. This ensures accurate color reproduction for skin tones and products. CRI 90+ is acceptable for background or accent lighting, but key lights require 95+ to avoid post-processing headaches.
Can LED strip lights replace studio strobes for photography?
For product and video work, yes—high-output LED strips provide continuous lighting with accurate color. For high-speed portrait work, strobes still offer more power. Modern LED strips excel at consistent, flicker-free video and detailed product shots.
How do I power LED strip lights in the field?
Use battery packs with voltage regulators for DC strips. USB-C panels accept power banks. For long shoots, invest in V-mount batteries with D-tap to DC converters. Always calculate runtime based on amp draw and battery capacity.
Are RGB LED strips suitable for professional photography?
RGB strips excel for creative effects and background color. For key lighting, ensure RGB strips also offer high-CRI white light (like the ULANZI VL49). Pure RGB strips lack full-spectrum white and produce poor skin tones.
What's the difference between lumens and lux for photography?
Lumens measure total light output; lux measures intensity at a distance. A 1,000-lumen strip produces 100 lux at 3 meters. For photography, focus on lux at your working distance—product tables need 500+ lux; portraits need 200+ lux.
How long do LED strip lights last in studio use?
Quality LED strips last 50,000+ hours (17 years at 8 hours daily). Heat degrades lifespan faster—ensure adequate ventilation. Cheap strips may shift color temperature after 10,000 hours. Professional-grade strips maintain consistency throughout their rated life.
