Default LED color temp issue

I upgraded all my lights to LED, it draws so little power! I'm really happy with the swap but the color is too cold I'd like it to be a little warmer. Has anyone used a filter inside the lens of the lights to tone it down? Also, I noticed a weird vision issue with the LED's. When they are dim and I move my hand in front of them I get this weird "tracer" type phenomenon, but it doesn't happen with the halogen bulbs in the same scenario. I'm thinking it's the color temp, but it's really annoying to function that way in low light. Has anyone else experienced this? Am I crazy?

Just buy warmer LEDs. Everything is available these days. Probably cheaper than a filter, and very likely more effective.

As for the "tracer", you are probably seeing a strobe effect from the pulse-width modulation from your dimmer. You don't see it with halogen because the bulb doesn't have time to cool between pulses. LEDs turn off instantly. Try replacing your dimmer with one designed for LEDs.

Warm is 3000K to 5500K temp higher gets whiter and into blue tint. When you buy them its usually listed on the box somewhere. You probably have higher temp ones and makes everything look weird.

you can search for my write up of LEDS- I used bayonet to bipin adapeters and phillips 12 volt leds ( home depot)- cost per light about $7

the phillips are about 2800 as i recall, I prefer a "browner" light than a bluer or bright white

and as above you are seeing a modulation...same as moving your hand in front of an old CRT tv

I replaced all of mine with LEDs too, but same warm white color as the original. It is no brighter, but I love the miniscule power it draws. $12.99 package of 10.

Amazon has them, mine was this brand - XCSOURCE at this link:

I don't know if all RTs use the same bulb type but this just happens to match the old ones I had.
