Need some really bright LEDs? Contact us now!
White Through-hole 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. The difference of White SMD LED and the white Through-hole LED is the diversification of the angle, diffusivity and spotlight. In 18
years, we supply the white Through-hole LED with high efficiency, high
luminance, low light attenuation has been recognized by our customers.
1, Color
is wide enough to suit every one's needs and taste: White Through-hole LED
typical color temperature is 2000K warm Yellow LED, 2700K warm white
LED, 3000K warm white LED, 4000K white LED, 5000K white LED, 6000K white
LED, 7000K cold White LED, the maximum color temperature can reach
above 50000K color temperature. White Through-hole LED has been widely in the
indoor lighting and outdoor lighting because of good heat dissipation,
low light failure, high brightness.
2, High
color purity: We can supply White Through-hole LED with high index white LED
(Ra> 80), common index white LED (Ra less than 80) and super high
index white LED (Ra> 90) LED. Common index white LED used in
conventional lighting or electronic components. high index white LED
used in lighting or fill light products. Remarkable LED lamp beads made
of the product's realism will be greatly enhanced. The light produced by
the High rendering index LED will make the things more vivid. We can
also customize low SDCM (Color Tolerance Adjustment ) products to meet
the high requirements of the customer.
3, Colorful epoxy: Water clear, white diffused, pale white diffused.
4, Variety
of angle available: 5 degree through-hole LED, 20 degree through-hole LED, 30 degree through-hole LED, 40 degree through-hole LED, 45 degree through-hole LED, 60 degree through-hole LED, 90 degree through-hole LED, 120 degree through-hole LED, 140 degree through-hole LED ect.
5, Variety of
shape/size available: We supply the white SMD LED, such as: Round through-hole LED, Straw hat through-hole LED, flat top through-hole, Ellipse throuh-hole LED, 3mm Through-hole LED, 5mm Through-hole LED, 8mm Through-hole LED, Rectangle Through-hole LED(2*3*4 Through-hole LED), Square Through-hole LED and so on.
6, The length of pin: LED Lamp's pin can be 17mm, 29mm,
90 degrees bent feet, braided pin and so on. Tips: taping pins can
operate on a robot, greatly improving the efficiency of manual plug-ins.
We
will do the High temperature resistance testing and 10 hours ageing
treatment before the product out off the factory, which can ensure the
stability of each product. Our LED products have 5 year warranty. Please
believe that we are the best supplier for your light-emitting diode.

Granite rock characteristics
Granite and basalt are both volcanic rocks, but they form under different conditions. Granite is an intrusive igneous rock that forms deep underground when magma cools slowly under high pressure, resulting in a dense, coarse-grained texture. Basalt, on the other hand, is extrusive, forming from magma that cools quickly on the surface, giving it a finer and more uniform structure. The famous Huangshan Mountains were created when underground granite was uplifted to the surface through tectonic activity. Once exposed, this granite was shaped by erosion, especially by water flowing along natural fractures, carving out towering peaks and dramatic rock formations. These isolated peaks, known as "stone pillars" or "solitary peaks," eventually formed the iconic peak forest of Huangshan, including the famous "Pen Flower" rock formation. Some of these peaks rise over 1,000 meters, with more than 70 such peaks found in the region.
As water flows through the vertical joints in the granite, it gradually erodes the rock, creating deep gorges. These gorges often narrow into steep-walled ravines, where the sky appears as a thin line above—this is called the "First Sky Line." Unlike limestone, which dissolves easily, granite is resistant to chemical weathering, so it rarely forms caves. However, water can still carve irregular cavities or gaps between boulders, especially in areas with stone egg landforms. Examples include the Water Curtain Cave, Lotus Cave, and Squid Cave in Huangshan.
Hot springs are a significant feature of granite mountain regions. Known for their mineral-rich waters, these springs are not only scenic attractions but also have therapeutic benefits. For example, Huangshan and Lushan are famous for their hot springs, which contain small amounts of naturally occurring radioactive elements like cesium, believed to be beneficial to health. These waters are commonly used for bathing and represent both a tourism asset and a valuable natural resource.
Most granite landscapes in China are found in the eastern regions with high rainfall. The abundance of water contributes to the formation of numerous waterfalls. In areas with developed granite peaks, waterfalls like the Herringbone Falls, Baizhang Spring, and Jiulong Waterfall are common, adding to the natural beauty and ecological diversity of these regions.
