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.
MY larger point is 1:1 replacement is pointless when I can whip out something the size of a Mars bar that puts out more light than my car's headlights. For two hours. Off a 3 hour USB charge. And LEDs are cheap. They used to not be but they're getting stupid cheap. Especially when you factor in the power savings. Grow houses became effectively invisible once LED lights became viable. Los Angeles is saving $5 a year per streetlight. The switch cost is already paid for. So yeah - LEDs aren't bulletproof and they aren't magical but they absolutely, positively kick the shit out of incandescents for almost any application. Yeah they suck ass for cinematography of any kind. The awesome part is in addition to the flicker the RGB ones have the same peaks as the CMOS most cameras use so they look all kinds of jacked. But I ain't a cinematographer so no fucks given.
