Bulbs on fire
OK, most of you saw the endcap I posted a while back, and we all blamed the endcap. It's happened again, but this time I got a better idea of what is happening, I think. I believe the bulb is getting hot enough to start melting the endcap, as you can see here, the melted area goes right around the bulb.

I wonder if there is something wrong with your bulb? I use the coralife end caps and have never had a problem with the VHO on them even though there suposidly for NO tubes.

That is the feeling I have had all the time. It looks as if the bulb is in contact with the endcap. In addition the temperature probably exceeds the rated temperature of the endcap. Hence the melting.

What type of ballast are you using?

Tony, the bulb(s) were about a year. Only the end got hot. I could hold the bulb anywhere past the first few inches. The endcap couldn't be touched by my bare hand for about 15 minutes after the lights were turned off.
Chris, I'm using a workhorse 7 ballast.

Do you think bulb age could be a factor? A year ... what is the recommended change-out schedule for these. Are they actinics? Isn't that 8-10 months (I ask, feeling suddenly very self-conscious about the 18-month old actinics on my setup
)
