1. Doulight induction lamp source Advantages

(1) Better light distribution in transverse space, light uniformity and soft.

(2) Use high quality special designed magnetic core material for induction lamp, low heat consumption, lower energy loss, stable performance, with better applicability and uniformity.  

(3) Mercury: Special dispensing of mercury, high purity, not volatile.                     

(4) Phosphor: High-purity, rare earth fluorescent phosphor with luminous efficiency.         

(5) Gas: Purity rare

2. Doulight Induction ballast Advantages Long life and high efficiency Ballast:

(1) American IC;

(2) Japanese MOS tube;

(3) Lighting protection device.

(4) Special anti-surge protection circuit

(5) Thick PCB, big panel, scientific circuit design

(6) 6 patents

3. Doulight Induction Lamp shade advantages

(1) Material : Shell is made of shock resistant high pressure die-casting aluminum.   Light panel is made of heat resistant toughened glass (optional). Luminous efficacy is above 90%.

(2) The heat dissipation structure ensures the luminous flux high output and reduces the attenuation of reflection coefficient.

(3) Thickness: 1-1.2 mm, strong and tough

(4) Reflector : High pure aluminum anodic oxidization reflector with special designed is better for light distribution effect, which support excellent optical performance.

5. Induction light Product features

(1) Light uniformity of the space can enhance uniformity of illuminated surface. Compact and integrated structure can match with various types of small size lamps to show different space lighting effects.

(2)Light-emitting surface area, compared with the point light source, lower surface brightness, but soft light.

(3) No filament or electrode, lifespan is up to 100,000 H, which is 10 times of that of fluorescent, 6-7 times more than MH and HPS.

(4) Luminous efficacy is more than 80 lm/W, power factor≥0.98. Low lumens consumption. Total harmonic distortion ≤10%.

(5) Excellent light capacity. The white light of induction lamp has complete spectral distribution and most is visible light, so the luminous efficacy is 20% higher than energy-saving lamp in the same illumination.

(6) Good heat dissipation. Separate installation of ballast and light source is more convenient for heat dissipation.

(7) Energy saving: save up to 80% compared to incandescent lamp. Instead of HPS and MH, achieve energy-saving 40~50%. 120W induction lamp can replace 250W HPS.

(8) High color rendering, CRI is more than 80%.

(9) Wide color temperature: 2700~6500K. It is suitable for different occasions.

(10) Start time: instant, less than 0.5s, to avoiding the potential safety hazard.

(11) Operating temperature: -30~+50. Strong capability is resistant to vibration.

(12) No flicker and glare provides maximum eyesight protection.

(13) Easy to install and easy to take away and dismount, to reducing the install costs. The connection of low frequency bulbs and ballasts can be extended.
