Sorry if it came off that way. The larger point im trying to make is that LED tech isn't always a great 1:1 replacement for incandescent and that doing LEDs correctly is darn hard. Both have their places and we shouldn't use LEDs as a replacement in all applications.

Also I wanted to mention that the entire advertised life of the bulb is unlikely to get realized. While the bulb has a theoretical life of 10k hours. It is unlikely to be realized due to the poor construction of the subcontinents, poor thermal management, and poor power rectification in the design. This is true for incandescents too but is much less of a problem when the bulbs are replaceable and $1 each.

My third point is that a lot of great tech dies at the margins for retrofit applications. Yeah LEDs might look great on street lights and are a good choice for new construction but once you factor in retrofit costs it may be cheaper to use the existing HPS bulbs in street light fixtures. LED fixtures need to be designed from the ground up and are sensitive to all sorts of factors that incandescent lights care little about therefore initial cost is high.

Also for cinematography purposes the LEDs may have a ripple flicker the really fucks up your shots so keep that in mind.
