14 5W LED bulbs comprehensive cross-test
LED lighting products have entered the pioneers of people's lives and are LED bulbs. However, the LED bulbs, which are said to be energy-saving, durable, long-lived and harmless, are presented in front of ordinary people, but they are mixed and mixed, and users are inevitably confused about the choice of LED bulbs.
Randomly selected 14 LED bulb products from the market, tested several key application indicators, and made a horizontal comparison from the application point of view, trying to give the user a general impression.
Second, the selection
Ordinary employees who are not familiar with LED lighting technology purchase directly from the market, such as storefronts, Tmall, Taobao, No. 1 store, etc., all retain invoices.
The 14 products are all new products officially available from the manufacturer. The nominal power is from 5W to 6.3W. This evaluation is based on the 5W level.
Third, test instruments and software
Distributed photometer: remote GO-R5000, test product's electric power, luminous flux, light distribution
Integrating sphere: remote PMS-80, test the light color parameters of the product
Strobe tester: remote LFA-2000, test product strobe parameters
Lighting Analysis: Lighting Analysts AGI32 V2, calculating the lighting effects of analog products
Fourth, product identity
Because the model marking methods of different manufacturers are very different, and some products have no models inside and outside the packaging, this evaluation first encountered the problem of being unable to verify the correctness. For the convenience of writing, this evaluation starts with a simplified name for the product, as shown in Table 1.

For the white LED, We have a variety of color temperature to select from.
For instance: White 3528 SMD LED with 2700K,White 3528 SMD LED with 2800K,White 3528 SMD LED with 2900K,White 3528 SMD LED with 3000K,White 3528 SMD LED with 3200K,White 3528 SMD LED with 500K,White 3528 SMD LED with 4000K,White 3528 SMD LED with 4500K,White 3528 SMD LED with 5000K,White 3528 SMD LED with 5500K,White 3528 SMD LED with 6000K,White 3528 SMD LED with 6500K,White 3528 SMD LED with 7000K,White 3528 SMD LED with 7500K,White 3528 SMD LED with 8000K,White 3528 SMD LED with 9000K,White 3528 SMD LED with 10000K,White 3528 SMD LED with 15000K,White 3528 SMD LED with 20000K,White 3528 SMD LED with 30000K ect.
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.
We supply kinds of 3528 SMD LED with different wavelength from 365nm to 1550nm, which include the visible LED and the invisible LED.
In this catalog, we mainly introduce the 3528 White SMD LED of visible light. 3528 SMD LED, size is 3.0*1.4mm. For this white SMD LED, we can package with single chip 3528 SMD LED or 2 chips 3528 SMD LED and the power can be 0.06W 3528 white SMD LED, 0.1W 3528 white SMD LED, 0.2W 3528 white SMD LED, 0.5W 3528 white SMD LED and so on.
The white SMD LED's voltage is 2.8-3.5V.
3528 white SMD LED is deeply loved by their users because of the small size, the high brightness.
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.
