No pic's but replacement bulb choices would be Radiums de and the Iwasaki 50k de . To replace the pc's I would go with UV 454's ..
Do not dismiss the Phoenix 14k de bulbs either .
HTH
Sorry about the delay . Had to do a skimmer breakdown/cleanup
Proly AquaCave . Make sure to remove the pc bulbs to check if they are straight or square pin connector .

I am of the thought that you have two 65 watt pc's which equals to 130 watts .
Never mind I see that it is a current . They did make one like that back in the day..
Here you go . PA has them
