We are manufacturer of LED light bulbs, You can buy samples from here to test our LED light bulbs. Welcome home user using multiple white LEDs or high power LED as a replacement for tungsten filament lamps.You will saving at least 50% cost because you buy directly from manufacturer.
Better energy efficiency over incandescent and most halogen lights, Saving energy 80% to 90%. (How many watts LED lamp will use when replace incandescent bulbs, halogen bulbs, CFL lamps? The comparison approximately: Incandiscent 60 Watts =halogen 60 watts =Fluorescent tube 14 watts = CFL 13 watts=LED 6 Watts for same light output. ) Very long operating life (up to 100,000 hours) Low voltage DC operation or Mains voltage operation (Input from AC85V TO AC265V) Cool light output (no UV or heat energy) Viewing angle options: Narrow angle 15~20 degree, Medium angle 40~60 degree, Wide angle 90~120 degree.Compare with fluorescent tube and CFL lamp, No fluorescent paint and gas contamination of premises, LED lights is green light source.Any combination of lighting colors, White LED Color Temperature Options (in Kelvin) : Warm white(2700K to 3500k), Pure white(5000K to 6500K), Cool white(up to 8000K), Amber, Orange, Red, Cyan, Blue, Royal Blue, Green). Before you order it, You must understand What do "cool white" and "warm white" mean?
