Tubular Aquarium Lamps vs Plants
 
I'd like some help again :-) I'm trying to figure out what Kelvin rating these lamps give off in my 10 gallon, I always only had florescent tubes, this tank however has tubular lamps.

The only thing I was able to find that comes close to daylight is 2x25W Clear bulbs from Zoomed, which is what I put in there now...and judging its spectrum by the eye it looks ok BUT will it be ok for my plants in the 10 gallon :-?

Well, it takes time to read all this stuff...:roll:

To your initial question, are these screw-in bulbs? If yes, I expect they are compact fluorescents, recent inventions that produce more light for considerably less energy (watts) so economical as well as environmentally friendly. They work quite well over smaller tanks, and they produce very little heat (one reason they use less energy, heat is high energy). They come in various "colours" like warm white, cool white, natural white...all similar to regular fluorescent tubes. The kelvin rating will be similar for both types, natural white something like full spectrum around 6500K, cool white more blue so higher, etc.

If Zoo Med make these, you can probably find the K rating and other info on their website. DrsFosterSmith Fish Supplies: Fish Tank & Fish Care | DrsFosterSmith.com is a good place for this type of info, if they carry these bulbs.

Couldn't find them @ Drs site.
But yes they're screw ins and no they do not get warm at all (lil temperature after 11hrs but not warm as what I'm used to from the florescent tubes at all).
The org one's in it gave off this yellow's light, didn't like that AT ALL so now I bought the clear daylight version of these kinda bulbs and that looks better and the new ones are also 25W rather then the old 15W.
Despite not finding the EXACT detail, I'm hoping form the lights 'looks' my plants will be fine (can you tell new stuff that I'm not used to in my old tanks easly makes me worried about my new tanks now lol)

Sounds like these are compact fluorescent bulbs. The "yellow" light is warm white, higher in red. Cool white would be the opposite, more blue so it appears "cool" as the term says. Natural white light is close to full spectrum, so it should be fine for plants. I've no experience with these, but this is what some plant authors I've read mention.

I never had experienced them neither...but I guess I will now cause the way the hood is made I can not rebuilt it in no way to use the normal T8 or nothing. And since I honestly don't wanna built a hood for this as well ( at least not right now) I will give it a try and see how the plants and shrimp respond to it. All else fails I have yet another winter-time project for the next hood in front of me LOL

I can keep you posted how its working, specailly since I can make nice comparison with the 55g with the different light cause both where planted at the same time with almost all the same plants.

They should be fine for the plants to use, however I would check the wattage of your hood. With screw in compact flourscents basically all of them will fit into the same socket from 7-100+ watts. However not all fixtures are made the same, they have wattage ratings. I would check your light fixture it should have a "use only ##watts or lower rated bulb(s)" You said you went from 15watt to 25watt light, you need to check and make sure you are not exceeding the rating of the fixture. If you go over slightly (1-5watts) it should not be a problem. If you go too far bad things happen. I didn't know at the time, but I put a 100watt incandescent in a 75watt rated lamp fixture, worked fine for a month. Then one day the bulb just exploded........

I believe florescent bulbs work different. You may not have to worry about them exploding, but they will not run at full wattage. But I'm not totally sure on that.

With an incandescent fixture, the wattage ratings are to protect against too much heat from both the bulb and the current draw through the wires; either which could cause a fire. With CFL, heat and current draw should not be an issue.

Thanks for your concern, but I checked before I bought the new one's, hence the reason I bought 25W cause that's what it said "Use 25w MAX" ;-)

Frustratious - I haz it! :evil:

I know y'all suggested these lights would work for my plants. But day after day seeing this tank next to my desk now, its so 'dim' like a never ending sunset in the tank dim. I really don't like it and I'm honestly worried it will not be good enough for the plants (I know you all have experience and said it will be, I'm just worried this is not sufficient)
And these screw in bulbs, really what I can find is what the tank had when I got it or what I just bought and neither one seems 'bright' (you know like the life glo bright) even having bought the higher 25 watts one :roll:

And I don't wanna have to buy a new hood on this tank so now I'm sitting here inspecting the existing hood with the screw in's and wondering how well of a job a drimmel will do to cut that plastic housing out so I can put a normal fluorescent fixture into it (I have 2 spare one's from the other tank each 18") cause they would fit perfect and I know I can get the lights I want for it.

I donno what to do really :roll:
