What are advantages of ed28 metal halide lamp over a ed37 metal halide lamp?

Answer 1

There really are no advantages of an ED28 over an ED37. If they are both metal halide lamps then the only difference between them, provided they have the same wattage and color temperature, is that they have different dimensions and different size bases. They will require different size sockets and will likely require different ballasts.

Answer 2

The ed28 metal halide lamp typically has a smaller size and lighter weight compared to the ed37 metal halide lamp, making it more suitable for fixtures with space constraints. Additionally, the ed28 lamp may provide more focused light output due to its smaller diameter, which can result in better light distribution and efficiency in certain applications.
