LedTek offers all LED wall series as BL- and WH-series. LED cabinets of the BL-series offer a standard brightness up to ca 1500 Nits. All WH cabinets are offered as a daylight-suitable series with a brightness of ca. 4500 Nits. For more than 85 percent of all usages, the standard brightness is sufficient. However, if the LED wall is supposed to be exposed to extremely bright environments, like shop windows or outside in direct sunlight, the purchase of a WH-series can be reasonable. LedTek outdoor series are waterproof.
