Warming up cool white LED

[Deleted member 9648]

We have an issue with some 30w LED floods we installed as uplighters. This was a bit of a rush job without a proper spec. The users are complaining that the lights are too 'cold' and have asked us to replace them with a warmer version. Fine, we could order warm white versions but there are a number of fittings, they are not going to pay the additional costs, and we don't want to bear them either as we provided what they asked for as far as we are concerned.
So does anyone know of a suitable self adhesive film which could be used to warm up the colour? As they are uplighters it would not show,and there would be minimal heat to affect it. Perhaps there is something like that in the theatrical lighting business?

Not used them myself but maybe worth a go before swapping fittings.

Yes you can get lighting gel which changes the colour temperature of lamps

You are probably going to need CTO which is colour temperature orange it changes the kelvin of the light but when using any gels you do loose light level

Try these
Lee lighting filters

But it's expensive stuff 70 quid a roll

Maybe try photographic suppliers as well.

Would a sheet of it not be sufficient?
If you ask most suppliers they'll send you a swatch book for free.
