Grille lights, as common recessed lighting fixtures, require the use of straight-tube light sources. Currently, the mainstream choices are LED tubes and traditional fluorescent tubes. The core differences between the two are as follows:
1. LED Tubes
Power Consumption: A single LED tube typically has a power consumption of 10-20W (e.g., an 18W tube replacing a traditional 40W fluorescent tube), achieving energy efficiency of over 60% (data source: US Department of Energy 2021 report).
Lifespan: An average of 30,000-50,000 hours, far exceeding the 8,000-15,000 hours of fluorescent tubes.
Compatibility: It is important to note whether it is a "direct replacement type" (compatible with electronic ballasts) or a "bypass type" (requires ballast removal).

2. Fluorescent Tubes
Types: Primarily T5, T8, and T12 specifications. T5 has a tube diameter of 16mm, and T8 has a tube diameter of 26mm (International Electrotechnical Commission IEC 60081 standard).
