We supply kinds of 5050 SMD LED with different wavelength from 365nm to 1550nm, which include the visible LED and the invisible LED.
White SMD LED, it is the light produced by the blue color chip which is transformed by the special LED fluorescent powder. It does not have a fixed wavelength range and value, which meas White LED need the coordinate value of X, Y and color temperature to represent it. In 18 years, we supply the white SMD LED with high efficiency, high luminance, low light attenuation has been recognized by our customers.
In this catalog, we mainly introduce the 5050 white SMD LED of visible light. 5050 SMD LED, size is 5.0*5.0mm. For this white SMD LED, we can package with single chip 5050 SMD LED or 2 chips 5050 SMD LED and the power can be 0.06W 5050 white SMD LED, 0.1W 5050 white SMD LED, 0.2W 5050 white SMD LED, 0.5W 5050 white SMD LED, 0.6W 5050 white SMD LED, 0.8W 5050 white SMD LED, 1W 5050 white SMD LED, 2W 5050 white SMD LED, 3W 5050 white SMD LED and so on.
The white SMD LED's voltage is 2.8-3.5V.
We have a variety of color temperature to select from. For instance: White 5050 SMD LED with 2700K,White 5050 SMD LED with 2800K,White 5050 SMD LED with 2900K,White 5050 SMD LED with 3000K,White 5050 SMD LED with 3200K,White 5050 SMD LED with 500K,White 5050 SMD LED with 4000K,White 5050 SMD LED with 4500K,White 5050 SMD LED with 5000K,White 5050 SMD LED with 5500K,White 5050 SMD LED with 6000K,White 5050 SMD LED with 6500K,White 5050 SMD LED with 7000K,White 5050 SMD LED with 7500K,White 5050 SMD LED with 8000K,White 5050 SMD LED with 9000K,White 5050 SMD LED with 10000K,White 5050 SMD LED with 15000K,White 5050 SMD LED with 20000K,White 5050 SMD LED with 30000K ect.
5050 white SMD LED is deeply loved by their users because of the small size, the high brightness and 5050 white SMD LED have the cooling copper at the bottom, which can make the product to get out of the heat in time.
It is often used in LED lighting, LED Lamps, LED backlight, LED panel lights, LED furniture, landscape LED, LED Lighting, LED Lighting, led Backlight, LED Panel Light, LED Furniture, LED Photo Light, LED Aperture, LED Toys, grow light LED, fill light LED, LED aperture and other lighting products.
