recessed lights

[rverdlm]

We have used the recessed lights over our chairs for reading lights since we bought our rig and loved them. In the last month or so I've had 2 of the lenses fall off into my lap. (boy, are they hot) I found 2 others that were damaged. The reason the lenses fall is that the ears on the lenses have melted. Has anyone else seen this? I've only used 10W bulbs, I've checked the voltage (13.6V). I don't know what else to check. I talked to Kent and he sent new lenses, but said it was the first he's heard of this problem. Any advice would be appreciated as we are now afraid to use these lights.
