I like the way that incandescent light penetrates snow fog and particulate matter.
I love the color rendition. Everyone always says it's better outdoors, which is of course correct, but then it dawned on me I like it so much indoors because I painted most of my house in very light earthtones, shades of brown.
I like the ease with which you can focus incandescent light sources. Yes, LEDs are finally getting up to a thousand+ lumens, but I have yet to see anyone collimate these lumens into a real thrower. I admit I have little experience, but I've yet to see any LED that can out-throw my 1185, and that's only a KT4 turbo head.
I think there is a somewhat visceral experience with high power incandescents (and my biggest stick is an 1185 so it's not all that big) going back to controlling fire, etc. It makes the boy in us all giggle. LEDs just don't do that.
All that being said with manufacturers now beginning to dip their feet into the neutral and warm LED waters, I'm probably done with incandescent lights. My A2s are awesome, I'll probably have them forever, but I don't EDC them anymore. My Red A2 is on my nightstand, but that's the only one in daily service. My Megallenium 1185 only comes out for special occasions (although PWM brightness control is awesome in incandescent), and my 6P has been modified with a Malkoff M60W.
My EDC is a Ra 100ww, and my two latest purchases are Neutral Quarks (Mini and RGB).
I just don't see any new incandescent tickling my fancy, I have all that I could possibly need.
Now, HID, there's another animal...
