LED vs Halogen bulbs

That I agree with you 100%, I paid extra to get 4500k leds and they are not the ones above :), I dont like the bluish ones and that is worse for your eyes. Reminds me of when everyone put in those blue-tinted bulbs to make their halogens look like HID and all it did was give you fewer lumens with bad coloring for your eyes.

i work with led elsewhere and we find even 4500k is bit too blue for most folk. 3500 to 4000k is the preferred range. we do use a fair bit of 4000 to 5500K for mid height. it gets insanely blue for high bay - a lot of 6500k. most folk like something warmer in the lower stuff.

4500 for indoor lighting is a bit too white, it's more sterile. Not sure why that is, I have 2700-3000k LED throughout my entire house. Most OE HID headlights are 4300-4500 which is natural daylight.

that's considered quite warm. 2700 - 3500k is the range i target flower bias grow lights. it's the same as mid through late summer light. 4000 - 4500 is the range targeted for veg bias and it's really blue at the upper. it's equivalent to spring thru early summer light.

There's a huge new house that just got built in my town, it's filled with what must be 5000k or 6000k LEDs. Like, way too many lights - under the stairs, outside, in every room. You can see the whole inside of the house from the street, and they're super "white". I don't think they ever turn them off either. It gives me a headache just thinking about it!

I've got US Ellipsoids in my E30, and was running with an eBay 4300k 35W HID kit for a few years. I can tell you the colour temperature is way off with these eBay kits, this was easily in the 5000-6000k range. I have also had at least one ballast fail.

Light output was way better then sealed beams, but still left a lot to be desired.
I have a set of 50w Morimoto XB Ballasts and 9006 XB 5000K HID Bulbs waiting in storage to try out next.
A test firing showed these are between 4300k-5000k. No blue light at all.

I am using some LED Highbeam Lamps - Aukee 5000lm 6000k (6x CSP Diodes) which are quite a bit brighter then the halogen and haven't failed yet. (However they are too blue for my taste)

Makes me feel like I am in a hospital when the lights are that bright in a house. I don't even like 4000 in my house. it was hard for me to move to 3000 lol. The woman we bought our house from did the same thing she had recessed lighting everywhere, like even a small room like my office had 6 fixtures. The problem was in some rooms she had like 90 or 75-watt halogen floods in others she had Bright white LEDs, the contrast killed me. The entire basement was 75-watt halogens, I took almost 15000 watts worth of lighting out, I could warm the entire basement with the heat off those bulbs.
