    Thought I would start the new year with new tubes in my lighting units.
    But let me start at the begining:
    I decided to go over to T5's after having bought my tank with a canopy fitted with a set of halides. Loved the look but had heat issues which then became evapouration issues so when the canopy needed to be redone I thought that this would be the ideal oppurtunity to move to T5's. As I am renting my landlord was not to happy when I asked him if I could suspend my lighting unit from the ceiling so instead I got two chinese T5 54w Units with led moonlights instead of the well made local (Durban) ones.
    Anyway algae became a major problem and I eventually found that these had been supplied with the wrong bulbs - oops. So I purchased some of the cheaper well known bulbs as replacements. I wanted the more exspensive german ones but thought id save and move onto those later. So the cheaper ones pins broke easily and were not the quality I expected and was not happy with the lighting so after 4 months these also had to go. So a mate of mine got hold of some cheaper bulbs - german bulbs( anyway say they are made in germany on the bulb) from our local electrical wholesaler. Now these are Sylvania Aqua and Coralstars but wow what a difference. I still intend going for the "exspensive" german bulbs but thought I would try the cheaper german alternative first.

    Has anyone used these before and how do they last?
    At R150-00 a bulb I am not expecting miracles but expect them to do a lot better that my previous ones.
    Suppose the moral of the story as with everything in this hobby rather dont skimp on certain things and buy right the first time.

    there are a few guys on the forums that are using them, but lets wait for them to advise, have you used reeftek lamps ? I think Mekeel uses them on his tank and his tank looks awesome

    Hi i like the sylvania coral star as actinic and reefteck 10 or 12000 k ( R149.95 )white lights over the aquastar white.

    I replace the std oddisy bulbs with these and am very happy with them.
    I have since doubled up on these light units and the corals have reponded very well.

    I tried reefteks bought 12. 8 for the lights and 4 spare about 4 months ago. Have got rid of all of them. I was not happy with the quality or light. I have Odysea lighting units and am not sure if they are the cause of the problem. IMO the reefteks are odyseas with the Reeftek labelling. I also received good feedback on these maybe I just hit a dud batch. After 6 months a fan had packed up in one of the units and the screws are rusting on both. In the mean time I will be replacing these with stainless ones next week and will try source better fans.

    They looked dull. Use a combo of actinic and coral blue with the 12k's.
    The new actinics look much better. Will probably still use the 12K.

    Think that is the way to go. Hear they last longer as well.

    they are a bit pricy but if you consider the benifits over the one year ,i personally think its worth it.

    who can honestly garantee a globe or bulbs life but if a manufaturer claims 18months then at least you know you should be ok for at least a year.

    yeah giessemann is the way to go,11k aqua blue plus especially has a positive review from me!

    Dont right of ATI either they make brilliant t5's some claim them to be better even,very good bulbs with high output and life.

    Those sylvanias have lousy par-lumen/watt output in fact a osram 8800k t5 is a way better option if you not going for the big boys (ATI,Giesemann)
