Did my LED lamp burn my Nepenthes ventrata?

Hi...

I bought a Nepenthes ventrata on Amazon. After reading the FAQ on LED lighting at the ICS homepage, I bought a LED light. I ended up with a 150 watt, 90+ CRI, 3,000 K, 1,500 lumens bulb. I placed my light (which is a 40 degree flood) 17 inches above my plant and put the light on a timer. I gave the plant 12 hours on and 12 hours off. The plant is in a south facing window. But this time of year in Oregon, it is almost always overcast and it gets little light from the window.

I used this as a guide for my LED light:

This morning, I noticed that the top leaves were turning brown. Was it my light?

When the plant arrived it was a bit dry, so I soaked it in distilled water and then let it drain well. I put a little water in the pitchers and put it under my light. I occasionally mist it. The soil is moist, not dry and I have given it little water now and then. It is not sitting in water.

Here is a link to some photos. The first two are of the plant when it arrived. The next three photos show the brown on the top leaves.

Suggestions welcome,

I forgot to ad humidity and temp data....

The humidity in my house is between 60 and 68% measured at the plant. The house temps never drop much below 65 F (18 C) and the usual low is 68 F (20 C). It can get as warm as 78 F (26 C) during the late afternoons.

I hope this helps.
