Dependence on ballast. Ironically, the ballast itself becomes a redundant part of the Type A LED tube system. The ballast causes an additional power drainage through the system simultaneously with other components, thus decreasing the tube’s efficiency substantially. Plus, the ballast doesn’t last as long as the tube, leading to early repair or replacement costs of parts (or even the entire system). Tube replacement is strictly subject to ballast compatibility. Before replacement, users need to ensure that their new tube is compatible with the existing ballast.
Voltage and temperature sensitivity
LEDs require a stable temperature range—a voltage above the threshold value and a current below the indicated rating. Proper heat-sinking setup and electronically controlled voltage passage along with external regulation of voltage and temperature are required for proper functioning of the device. This calls for precision engineering using good-quality driver and fixture components.
While LED tubes seem like a huge capital expenditure, benefits in the long run far surpass the initial investment made. After all, at the end it is all about making your business smarter.
