You know, for the most part, I’ve been pretty unimpressed with the designs of the A-lamp “replacement” LED lamps. Â I’m not shooting my mouth off saying I have a much better design, but there is something about that diffused white globe atop the heat sink, which looks like a handful of fins. Â I actually kinda like the heat sink design, the fins are neat. Â If you’ve held one of those suckers when it’s been on for a while, that heat sink is HOT! Â Not Jennifer Lopez hot, we’re talking George Bush’s ears while telling the nation that Iraq had weapons of mass destruction hot. Â That is HOT!
I just turned onto a new design for the LED A-lamp from a company called the Switch Bulb Company – they are promoting an LED replacement A-lamp with a high CRI, a warm feel, and a pretty decent output. Â The difference? Â A lens-type “ball” atop the heat sink that shows each element and the heat dissipation gear inside. Â It’s actually quite a beautiful design! Â Check it out:
Pretty interesting design, huh! Â Switch is offering three models right now – the Switch40, Switch60 (PDF spec link), and Switch75 (PDF spec link). Â As you can probably guess, these 40, 60, 75 ratings are the replacement quantity of light per power consumption hint-hint to sell the “incandescent replacement” idea. Â The Switch40 doesn’t have specifications online yet, but the Switch60 claims 830 lumens at 13 watts, and the Switch75 claims 1150 lumens at 16 watts. Â Pretty decent! Â That 830 lumens figure is pretty close to an 850 lumen incandescent at 60 watts in terms of efficacy – if you look at an 850 lumen 60W incandescent, the efficacy is about 14.2 lm/W, but the Switch lamp is putting out nearly the same output at 13W, giving a near 64% efficacy!
Switch is showing two general colors – a “warm” at around 2750 Kelvin, and a “Neutral” colored lamp, more than likely a bit higher in color temperature. I’ve requested to get my hands on one of these, let’s see if that happens or not! Â I would love to see one up close!
