What is RGB Projection Technology?
RGB is the technology that makes galaxy projectors show millions of colors. Here’s how it works.
RGB = Red + Green + Blue
RGB projection uses three primary LED colors (red, green, blue) that mix in different ratios to produce up to 16 million colors. By adjusting the brightness of each LED, the projector can show any color in the visible spectrum.
RGB vs Single-Color LEDs
- Single-color LEDs: One fixed color, basic, cheaper
- RGB LEDs: Millions of colors, versatile, smarter
- RGB is 10x more flexible than single-color
How Long Do RGB LEDs Last?
- Daily use: 5-10 years before any noticeable dimming
- Occasional use: 10+ years
- With proper care: 15+ years
Does RGB Color Fade?
Not really. Quality RGB LEDs maintain their color accuracy for years. Factors that can dim them: heat (poor ventilation), voltage fluctuations, and physical damage. See our gadget care guide to maximize lifespan.
Is RGB Safe?
Yes! RGB LEDs are non-toxic, low-heat, and energy-efficient. They’re 100% safe for daily use, including in kids’ rooms and nurseries.
