The Sun Bulb features an integrated LED system, which means the bulb itself is not replaceable.
Why it’s designed this way:
- We use a highly specific, premium LED diode that requires direct mounting for performance.
- Mounting the diode to the transformer ensures peak efficiency and cooling.
- This integrated design allows for a high-quality, 30,000-hour lifespan.
- At 12 hours of daily use, your Sun Bulb will last for nearly 7 years.
The Gathera Tip: While we are working on a future modular version with replaceable parts, the current Sun Bulb's engineering focus is on maximum longevity to reduce electronic waste.
