How many audiophiles do you need to change a lightbulb?

Get LEDs; never have to change them.

I'm not paying $$$ for something I can DIY.  So first I sourced Russian made lamp bases.    Then after extensive research I developed my own braided filaments using .9999999 copper and tungsten and a material I prefer not to disclose (I'm filing for a patent) in what I call a Hyper Light Braid.  The braid creates an optimal distribution of photons across the visible spectrum--though as an older male I do have some upper frequency roll off and dont see deep purple as well as young folks.  My wife and kids can though.  Color temperature is controlled by the ratio of copper to tungsten to my material X.  

Next is the critical issue of bulb type.  While the conventional white frosted bulbs are more pleasing they obviously both filter and distort the source.  So clear bulbs.  But not glass.  Currently I'm using crystal specifically Waterford globes. Swarovski is for rich poseurs.   I use argon glass to fill the globe at 2 atmospheres.  I use a regulated linear power supply of course, rewired with Cardas wire and Wattgate plugs.  

The resulting light stage is very broad and deep.  I can see the precise location of every component in my big rig.  Shadows are very carefully cast with little excess penumbra due to the single point source nature that the braid creates.  The light is very revealing of surface imperfections in the panel faces as well as dust on the turntable plinth.  But truth is more important than beauty.  

So far, it seems that no one, not one commenter, has mentioned the necessity of burning-in the bulb for a minimum of 250 hours before passing critical judgment on the fidelity or balance of the light produced. Likewise the cabling supplying the current...

Then there is the issue of bulb substitution. Incandescent vs. fluorescent vs led.

Changing the light bulb is all well and fine but we audiophiles all know that you have to change the room first. It's a must.

The type of bulb natters too. Forget this eco rubbish, I can tell you that NOS light bulbs are best but they're not cheap. Russian / Chinese replacements might well be acceptable....or they might not.

You might need 2 for stereo or perhaps even 4. Mono light is best left to the sun.

And whilst you're at it, don't forget the switch - faders are out!

Of course there are some who will always insist that scented candles are better.
