This was a cool picture I took this weekend of my nephew bowling under the light system I installed for Glo-Bowl at a bowling center. Hey, you guys like beam shots The light on the left is the Phlatlight based scanner while the light on the right is a 150watt HTI based Martin EFX.
The lights are Intimidator 300 scanners, and each use either a cool white CBT or CST 90 (not sure which) driven at almost 15amps. I pulled the lights apart and couldn't quite get over the emitters to see which chip is running, but the over-all light engine in pretty simple. They need a pretty loud 60mm fan to keep them cool.LED Fluorescent are starting to make their way into stage and DJ lighting, although high end halide is only just started to get displaced.
First time I sert the lights up in my office and fired them up was when I learned they earn their "Intimidator" name quite well. At 15amps an at 21degrees these things are the retina equivelant of getting kicked in the head because they easily keep up with 150-250 watt halides. Given the smaller size of the emitter it's much easier to design an efficient and tighly focused optical system than halogen or halide bulbs. The light cones produced by these babies is razor sharp and easily projects up 200 feet.With my haze machines running in an open space under black lights it's like 'Close Encounters', and really show off what the super high current emitters can do. Nobody believes the lights are using LEDs until I show them the box.
What's facinating and worth chatting about are the minor issues the lights have that are inherent to led ceiling lights, and yet nobody but led strip would really notice (or know what to gripe about). First, of the four lights I have none of them quite match in terms of color. The bins used are just a bit off, and any sharp eyed flashaholic would cry 'shens'. One reason high quality HTI bulbs are expensive. Next, the lights use classic dichroic color wheels rather than any type of RGB source, and given the limited spectral response of cool-white LED's this creates very dim warm colors. Basically, if the color doesn't use blue as a component, it's so dim it's not worth using. However, given that mid and high end HTI based lights are using the same color wheels by all means these LED's can't be left out from using those same colors - ha. Somebody decided they wanted high lux marks for advertising while sacrificing all the warmer colors. Sound familiar? I'd love to see these same things running neutrals instead, and in the future I might just swap them out.
Brightness though in full white is flat out astonishing. I though about keeping one for camping trips and using my DMX board to pan them slowly through woods and have a little fun with the local flashlight group - until the cops show up that is
