Call Patty at the contact phone number listed on the website. She's helpful and interested. My main difficulty with Carley is that Patty's inquiries on my behalf to the technical department for (1)reflector dimensions not shown on the website and (2) quotes for non-standard (a)ceramic potting of bi-pin bulbs in PR bases and (b)cost of bulb ID scribing on the base of the PR bulbs have dragged on for three weeks.
Patty has a tendency to put a lower priority on acknowledging receipt of an inquiry than she does to attempting to ferret out the answer to your questions.
Unfortunately, Patty isn't always able to get a quick response from her internal sources of information.
