Juwel Duolux (80) Ballast Replacement

If your Juwel light does not lit or lits for small period of time only and then switches of regardless you&changed the bulbs, then you need to change the ballast. This is how to video for Juwel Duolux aquarium ballast replacement. I used Osram Quicktronic QTP-DL 2X18-24 ballast as it has two 18W bulbs. You&need a flathead and phillips screwdriwer and a wire connector if you use this ballast, plus adhesive for the cover. Juwel used black silicone sealer for the cover, cover is quite easy to remove with some caution for not using too much force. Hope this video helps if you have similar issue.
