## Questions & Answers

**Q: Does this fit oase button 18c**
A: It fits yes, however it wouldn't light up. I replaced the UV unit thinking it was faulty for £99 and still nothing, ended up buying a new complete UV unit and connected it as a separate unit to the filter. However I also purchase OASE lamp and that didn't work either. For the price its worth a go you could always return it? hope this helps

**Q: Will this fit jeboa?**
A: Sorry not a clue. Contact your seller would be my best advice. Good luck and keep sake.

**Q: Hi ,will this fit my Blagdon 6000 ?**
A: Have you checked to see if this is the same as the bulb you are replacing

**Q: Do these emit UV-A light? Or just C?**
A: Used on my aquarium As uv light if you have a pond then tube and more watts
