I bought the Hosa Technology LTE-519XLR4. Talking with them, I thought the wiring was going to be wrong but given the price difference form the A&H lamp, I was prepared to re-wire it. To my surprise, when I removed the cover on the XLR4 connector, the wiring was compatible with A&H equipment. So I closed it up, plugged it in and have been using it with no problems. It could be a little brighter though. Probably the A&H is better but a bit too expensive.
