> LED lighting is costly and complex enough that directional LED bulbs are more or less at cost parity with omnidirectional LED bulbs. In fact, true omnis are often more expensive just because LEDs are inherently directional. This is the first time in the history of lighting where omni wasn't significantly less expensive than directional.
There was that awesome Kickstarter awhile back for a nice omnidirectional LED bulb, I'm looking forward to its delivery!
> Truth is, there are very few scenarios where a high-output omnidirectional lamp actually makes sense. We're used to omnis because they were much cheaper to purchase than their more efficient, directional brethren and because it's convenient to just slap a bright bulb in a socket and say "eh - good enough."
With this I disagree. Open spaces such as a living room are perfect for omnidirectional lighting.
Indeed when I have lived in places with track lighting the annoying part was always trying to spread the light out enough to make it seem omnidirectional without having a bunch of bright hot spots around the room.
When I am cooking or something, sure, light up my working surfaces, but for general ambiance when I am at home I want the entire bloody room I am in lit up!
Now just do that while saving power. :)
Indeed, if you look at how recessed lighting is installed (and I'll be the first to point out that recessed lighting is generally stupid), there are a ton of cans installed in a grid throughout the ceiling to provide what is essentially uniform brightness in a room.
- benjamincburns 14y agoSorry for the late response, I just noticed this. First I'm not a lighting designer, I just used to work next to a few of them so I'm probably (definitely) overconfident in my opinions in this area. That said, I personally go back and forth on what you're saying. Let me qualify: when I say "directional," I mean uniform 180° or narrower. The real difference is in the optic: flood vs spot. You can get a surface mount 180° flood fixture (ceiling mount) or a well fit recessed fixture with something like a BR40 (good wide-angle disbursement) to do exactly what you're talking about. If you want wide-area lighting, stay away from PARs, MR16s, GU10s, etc. Are omnis in a stood-off fixture easier? You betcha. Is paying to light your ceiling necessary? Nope. All of that said, I hope they get dirt cheap but efficient omnis out there too. Forcing the general consumer to think about stuff like this is a barrier to entry, and broad swaths of people being more efficient is a Good Thing indeed.
