Color correct new LEDs

[HHaase]

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.

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!

Looks great!!

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

Erik, thanks for the advice. I'll look into custom cutting that Rosco glass next spring!

[Erik Olson]

Eric, I believe the cut sheet on the American linear states CRI of 80, which is about where most consumer-oriented product is sitting. If you hunt for "HD" products from Sylvania (and others), you'll find 95CRI stuff out there in replacement lamps (A15; A19; Par20; Par30; Par38) and so on. In linear product... it's a little tougher.

For significantly more money, we have the Acclaim Flex III, which is available in 2700, 3000 and 3500K at >96CRI. We haven't seen anything higher - yet.

Thanks much!

I would suggest anyone who's putting LEDs into their living area to go for the HIGH CRI lights. 80CRI consumer lights are harsh and ugly.

After being really unhappy with the blue/white LED lights in our Bambi, the first thing I did when we got our new 2015 AS was to put gels in all of our lights. Took about 10.00 and a half an hour to cut all the little circles and I can easily say it's the best investment I've made in our Airstream. I put two gels in each light and the color is exactly the same as the warm halogen lights in the hood vent! I can't believe the difference it makes!

Here is a link to the photo gel if anyone is interested.

Here are a couple of photos where you can see the warmth of the light:

Valmog,
Wow! That looks great. I may have to try that myself. Was one sheet enough?
By the way, my Wife and I are fans of your blog. We love your photos and your talent for interior design.

[valmog]

Thanks, flyncloud And one sheet covered every light in our trailer. I put them in two thick. We also contacted the company to make sure it was safe….and they said it shouldn't be a problem. These gels are made to stand up to much warmer lights. Should be no fire hazard. Can't tell you what a difference it made!

What's the secret for getting the lenses out in order to insert the gel film? 2013 Flying Cloud. I don't want to mess up the light fixture. Thank you.

[abqdor]

Having just took possession of our '16 Flying Cloud, we too were disappointed in the "daylight" LED's from the factory. After investigating our options, we decided to go with the gel filters behind each lens. There were 15 LEDs in our Airstream, not counting the reading lights. The lens was very easy to remove, but a bit tricky to re-install. You just have to make sure that the lens tabs line up with the slots in the fixture.

We used 1/2 CTO which basically converts daylight to tungsten or 5200 kelvin to 3200 kelvin. I tried Full CTO, but it made the light too orange for our liking.
Whether the LEDs burn the color out of the CTO remains to be seen, but it was a very easy and pleasing fix.

Here is a link to the photo gel if anyone is interested.

I've attached pictures showing both daylight and warm white in the same picture. The top two pictures show both lights in the same picture. Foreground is warm white, background is daylight. Hope this helps.
