That was the first thing we did! Still waiting on my latest order to arrive - I'll let you all know if it worked, or not - then I'll have to try some of these suggestions. Thanks everyone. For now, our trailer is called "The Blue Light Special."

Hi there,
I light for film and TV and we use gels all the time to change the color of lights.
You will want to use CTO (Color Temperature Orange) or something similar. "Straw" is quite nice too.

If you pick up one of these: Lee Swatch Book - Get One Free With Purchase - Filmtools
You can test all sorts of gels (just cover the others with tape). You will most likely use a 1/4 straw or CTO or maybe 1/2, just remember that this will cut your light transmission rate.

I would also suggest sandwiching in some "minus green gel" (it will be slightly red) maybe 1/8 Minus Green as the LEDs have a bit of green in them.

I know LEDs don't run very hot, but if the gels are placed right up against them the heat (even the little bit) will eventually take the colors out of the gels and you will need to replace them.

Lighting Gel Sheets - Filmtools

Hope this helps.
Eric

Thanks Eric (and Erik) - I think a swatchbook is just what I need, plus some minus green.

It worked! I wrote a post on my blog about it: http://www.aluminarium.com/airstream/airstream-led-color

Glad to see it worked! The pink spike is giving ya that minus green effect in one gel so that's a great find.
In the restoration of my 74 Safari I was planning on using warm LEDs strips, but have recently thought about side light fiber optics with LED generators... Perhaps that's my next thread:-)
Cheers.

Nice solution for sure.

Looks like surface mount LED's inside the puck. Not easy to replace the actual LED's, so yours is definitely the better option.

I just want to add my thumbs-up to this thread. I found it a couple of weeks ago and ordered my filters/gels through Filmtools.com. Just finished adding the Straw and Minus Green to all of the LEDs. What a difference. It's so much less intense than the harsh bright white and blue overtones. Very happy with the results! Thanks to everyone who contributed to the thread.

Here's what I ordered -- haven't yet used the Orange (CTO):

Lee Filters: Gel Sheet 124
205 1/2 C.T. Orange (CTO)

Lee Filters: Gel Sheet 178
279 1/8 Minus Green

Lee Filters: Gel Sheet 205
442 Half C.T. Straw

Great! Glad it worked!
I'm re wiring and putting in 6 strips of these warm white leds (16 foot strips x 6) all on dimmers.

Should make a nice office / work space.

If you want to replace LEDs with warm, pleasant versions just look for the 3200K (kelvin) or below. 2700K is pretty warm, but should be very nice.

One additional word of wisdom: roll up the remaining part of the filter and put them in a closet somewhere. Eventually the UV in the LED will make the color in the filter fade and you will need to replace them.
Cheers!

I want to thank everyone on the thread here that shared advice about lighting gels.

We wanted to warm up the reading lights on both the front and the back of our trailer. I don't mind the ceiling lights being cool and bright, but when we're getting ready for bed or want to read we wanted a warmer glow. Here's what I did:

Before picture of the reading light with cool blue LED.


Cutting out the Rosco Cinegel #3407 Filter - RoscoSun CTO - 20x24" Sheet (only $6.50 from B&H Photo).


I know the gel looks very orange, but when the LED is shining through it'll be more washed out.

Putting the cut gel into the cap for the reading light.


The final result. The LED looks like an incandescent light bulb now.


Thanks again for all the tips here. It's what makes this site great.

I recommend cutting several spares out of the excess gel, because we're finding that the LED emitters, which do not emit appreciable IR, UV or heat, are burning holes right through the color layer on the gel.

This isn't dangerous in any way, but you will notice (after about a month of cumulative runtime) that the color in front of each emitter will be completely burned to clear.

For about $8.50 each, I have Rosco's "PermaColor" dichroic glass in these same gel colors. We just need to know the diameter of the desired lens (the size you're cutting the temporary gel product) and then you'll have a permanent solution.

If anyone is interested in high CRI 2700-3000K LED tape, I have a good supplier through my vendor, American Lighting. They offer dimmable Bright White (which is close to daylight 5000K); Warm White (3000K, which is really close to halogen); and Ultra Warm White (2700K, like table lamp color).

They come in a basic kit, and we can also provide L or T connectors, plug-in power supply or permanent install 12V power supplies. I'll post up some pictures of some in my rig next week!

Led cri

Hey Eric,
when you say high CRI, how how are we talking?
I wouldn't want to put anything below 95CRI in my living area, are they that high? Are they high output?
Cheers,
Eric
