◆ This is an auction for a Sunstar Strobe OCTA32U head. It's in beautiful condition, but the modeling lamp is burnt out, so it's being offered at a bargain price. ◆ I've confirmed that it fires when connected to a generator, but the modeling lamp doesn't light up. I can't remove the glass globe (the glass cover for the flash tube) to replace it. If it could be replaced, it would likely work perfectly fine... ◆ Therefore, I can only guarantee that it will fire upon arrival. I believe this is one of the higher-end heads from Sunstar. The exterior is very clean.
