R-1 Emergency Light Series
The R-1 series is a very common series of generic emergency lights that are rebranded by tons of companies. These have the most common style of emergency light, that looks like a dual-blub floodlight. Some companies like Lithonia with their 2nd generation ELM-2 units take some of the parts from these units and changes others. Some units like the Lithonia EU2C[1] is a direct rebrand of the R-1 series. While these units are generally low quality compared to something original from a brand name, these units can be gotten for super cheap, which is why they are so common.
