If you are at extremes you have 1/2 of power compared to light made for this temperature, as half of leds do not work at all :-)

No one will invent magic. Just get light with more leds.

If anyone else is wondering about a bag for the LS 1S I bought the manfrotto allegra 30 messenger bag, seems to work great.

I bought the LS 1c and I have mixed feelings. The output is great, color is consistent and neutral, the price is reasonable - but the construction cannot be done by a person who ever used it in practice.

1st of all it's very heavy. The light itself 2,7kg because of the big cooling fins at the back. I seriously doubt that there is a need for such big and heavy convector. The power adaptor and the control unit weigh 1300g. In total 4kg which is almost double of a 1x1 Tecpro Felloni HO. 2nd The are named studio but I never thought that they can be used hanging from top only. The reflection / flags seem nice but the construction doesn't allow you to tilt the lamp more than 15° down when it's mounted on a tripod because the flags cannot pass the mounting frame. I used it for the 1st time on an assignement and I it was a pain in the... I think I will demount the bottom and the two side flags. Any other suggestions welcome.

I admit that I don't like how many pieces it has:

LED Panel--> lemo connector --> Control Box --> XLR Cable --> Power Adaptor --> IEE Power Cable

That's a lot of stuff that can go wrong/break/get lost/etc.

absolutely! You don't want to do this with cheapo aluminum kit stands. A real light stand made from steel would do the trick, but they are a pain to move around if you aren't part of a bigger a crew.

Alas, ain't no perfect solutions! ; )

BTW, I just shot 3 days in a row with the LS1s and yes, it had the same issue for me: can't tilt down far with the barn doors if it's on a lightweight stand. Of course all of this gets even worse if you try to mount a softbox.
