Philips Genie 18w CFL daylight energy saver

I'll quickly check the phonebook and give them a call. Awesomeness!!! Thanx guys!

 

you mean you can find t5's at lower than 37 rand? or am i misunderstanding? i went to one of the sponsor LFS's today and heard that i can get t5's at friggin 700 rand! where on earth do you get them at such a low price then?

 

you can also y the Osram Skywhite, 8000k. really bright and doesent give off hat yellowy tinge. Plant growth will always depend on th amount of light.ie hours per day and brightness, as well as there factor like nutrients and CO2

 

Ferry that sounds like ATI lights - they are VERY special T5s

 

and VERY expensive... the LFS made the point that in the end whether i buy 5 t8s and ballasts, or two of those t5s the light and price will be kinda the same

Henk, where do you find tubes at a reasonable price then?

 

i buy it from Lamp House.... give them a go... i got some sylvania 54watt for R40 something a tube....

 

thanks, i just looked them up via google, i'll have a look this weekend.

 

Thanks for the tip Henk, always looking for affordable advise.

 

just phoned them, for freshaqua - white color - R70, grolux - R70 vat excl. yay. thats WAY cheaper than my nearest LFS... now to find a place that stocks ballasts to power them, builders warehouse?

 

Any electrical or lighting retailer will stock ballasts. Get dual 54W ballasts.

 

Where do you get the waterproof end caps from? Or do the ballasts come with appropriate equivalents?

 

lance try www.dorrypets.co.za - Lanzo is the owner tell him i sent you.... they are sponsors on the sister site MASA

Remeber lamp house is only open during the week as they are actually whole sale

 

Shot Henk

 

what?! shooters?! where? Tang bite please!

 

Makro has the Genie in stock. Was R59 for 4!

 

tell me do the light fittings get wet or did u seal them ?

 

Mmm interesting Q...

But any aquarium light fitting would get wet to a certain extent, no?

 

Lighting Warehouse has a 32W 6400K CFL Screw in type for R40... cant get info on the lumens per watt still checking on that.

and PnP has a 15W 6400K CFL Screw in type for R18...

IMO the CFL is great value for money and at 6400K it is going to be perfect for plants and you dont need to worry about ballasts...

 

Allow me to ask a few questions if I may....

What does CFL stand for, and If I am correct, it is not the wattage or lumens that matter so much in a shallower tank, but the kalvins? Let me say to liftcrazy that I really like your setup! Nicely done, I am thinking of copying it

 

CFL = Compact Flourescent Lamp

The Kelvin rating on any lamp becomes the critical element when maintaining Plants and Corals as each has their own very special requirements. Incidentally or not ush: both plants and corals thrive at a Kelvin rating of 6400/6500. Its just that the 6400/6500 "color" is not ideal in most tanks especially the reef setups as it gives off a yellowish color...

Remember that when dealing with CFL's you cannot consider that 1w of CFL equals 7w of T5 for example. You must always calculate it as it is, ie. a 20w CFL is 20watts of light for your aquarium.

One more thing, CFL's are most effective when the tip of the bulb is pointing into the tank and not if placed horizontally...
