Can’t find t5 bulbs for my fixture anymore?

Angelo Fatica · Sep 9, 2023

Hello all,

I have a 20” aquatic life t5 fixture that takes 4 16.5” 18watt bulbs. I can only find purple variants of these bulbs, nothing else. Is there any hope for these or do I have to trash my fixture? I can’t find anything that is not actinic or purple in the size I need.

Looks to me like that fixture uses proprietary bulbs. . . and I am guessing the company that made the fixture and bulbs is no longer in business. . .

Unless you find some NOS at a LFS or an online auction you are probably out of luck. . .

keep in mind I could be very wrong about all this haha.

If you end up needing to replace it this is basically what I used, though keep in mind it does not have any water proofing:

Amazon product

then throw in some ATI bulbs from BRS.
