JESLED Single Row T8 LED Bulbs 2FT 12W 6CCT Selectable Frosted | Single & Double Ended Power | Hybrid Type A+B

【WARM TIPS】- ⚠️Type A LED tubes are designed to directly replace old fluorescent tubes without rewiring, as they run on the existing ballast in your light fixture. But they have very specific compatibility limits, ❌so please do not take for granted that they will work immediately right after you plug them in. If you encounter any installation issues, please contact us. 【Selectable】 - Switch from Warm White (3000K) to Cool White (6500K); perfect for cozy homes, bright offices, or garage workshops. Includes all 6 color options in one light. And Frosted cover diffuses light evenly, reducing glare and eye strain. 【100% Universal Ballast Bypass (Type B, HIGHLY RECOMMENDED)】- Fits all T8/T12 fluorescent light fixtures, no need to waste time checking old ballast parameters! We highly recommend Type B (bypass ballast) mode for all users: ▶️10-minute zero-experience DIY▶️15% more energy efficient (no wasted power from aging ballasts)▶️2x longer service life (avoids unstable current from worn-out ballasts damaging the tube’s built-in driver). 【BRIGHT & ENERGY SAVING】 - Illuminate your space with 1680 lumens. Cut down 66% bill of electricity when you replace 17 watt old fluorescent tubes with high output 12 watt 2ft LED tube. 【LONG LASTING】 - High quality LED chips, no flicker, no noise, Long lifespan up to 50,000+ hours! These 2ft led lights can last 20+ years depending on use, eliminating maintenance costs and reducing relamp frequency. 【Bonus Plug-and-Play (Type A)】- This is an EXTRA benefit for only 10% of eligible households: Works *only* if your existing electronic ballast is clearly marked with [F32T8 (for 4ft)/F25T8 (for 3ft)/F17T8 (for 2ft)] (magnetic/T12/universal/dimming/emergency ballasts are NOT supported). If it fails to light up after plug-in, it is NOT a product defect — simply switch to the ballast bypass option below to fix it in 10 minutes.
