LED Bulbs in studio

Where are you buying those?

I have a couple Phillips LED's I got at Home Depot. The Halogen replacements for my tracklighting are a little icy, but one of the regular bulbs seems pretty nice.

The glowing bit on an LED lamp is called a light engine.

What the heck are you, a steampunk or something?

Or a Dr. Who fan ... (Is there a difference these days?)

Let's just say I'm very good at my job as an electrician in a very forward thinking, design oriented building. I've installed light bulbs most people didn't know existed. I try to keep up on trends.

I'm not Dr. Who. I'm Dr. Whom.

Use a cap across them?

I just got done doing construction on a new facility (I've moved! Hooray!) and I went through nine different types of LED bulbs before settling on one that worked for me for the two isolation booths we upfitted. I tried several different Sylvanias, Samsungs, Crees, Philips, and that Lowe's brand that I'm forgetting now (several different models of each) and all but one of them either looked terrible, diffused light in a weird way, had an awful color, weren't bright enough, or made noise. Most of them made noise. I had high hopes for the Cree bulbs because they're relatively inexpensive, seem to be sort of durable (although I did drop on in line at the store and it smashed), are omnidirectional, and have a nice hue, but they do make noise. A quieter noise than most of the others, but a noise, no less.

I finally got several of the Philips 75-watt equivalent dimmable LEDs. They look great and a dead-silent with the Lutron LED-compatible dimmers. They're like $39 each, but with three hours per day of useage (that seems to be what most bulb manufacturers consider "average"), they're supposed to last 22.5 years and cost like $1.14 per year in electricity.

I'll be putting a few more of those in some other strategic spots around the studio.

Are you talking acoustic noise, or electrical noise? I'm guessing the former?

FWIW, I too smashed an LED bulb, but as the LED's themselves were still intact, I just put it in a shaded lamp and it works fine (dim, but fine).

Yes, acoustical noise. The noise floor in the new isolation booths is pretty ridiculous, so even the bulbs with only minor "whining" were distracting to me.

for no noise try candles

Depending how well sealed his iso booths are, the candles may use up all the oxygen, I think singers have a thing about wanting oxygen

Candles are cool until they eat through the bottom of the paper plate they're on and tear into the vinyl on the stool that the plate is on or until the singer knocks one over, spilling wax all over everything.

I keep wanting to try lanterns.

Seriously, I have a cuppla hurricane lanterns that, when I've used them in outtages, have been very cool, atmospheric even.

But when I set out to record, I can't be arsed to set 'em up.

Anything with fumes, or anything that's a fire risk, is probably a bad idea.

I imagine LED rope chains are probably the safest.

LEDSupply.com sells some pretty LED flex strip. Comes in various colors including a couple shades of white, and runs off 12vdc. Pretty impressive amount of light for something that comes with a sticky back so you can just attach it to stuff.
