T5 Light Kelvins?

[s007]

Hi,
I have purchased Bulbs: 3 x 8Watt T5 bulbs, two white and one blue Voltage: 220-240V Frequency: 50/60Hz, Does any one know how can i find out how many Kelvins they have as far as i know the best one to have is between 6500k - 8800k . And as they are 8Watt each one, what other wattage can i get in T5's Dont want too much or too less light for my 8 Gall UK tank.

It doesn't say on the tubes, but is there any other way to find out.

By the way is it true that in future in next 2-3 years we should be able to get hoods with LED lights (more economical and cheaper)? lol

Thanks
Sergey

Hey Sergey, if you got boxes with the tubes it should say on the boxes

However if you don't have boxes I'll try and use my limitted knowledge of the spectrum to help you I think blues are around 10k. White's I would assume about 14k to 20k. But I'd take that advice with a grain of salt

Alternatively if you know the make of the tubes you could probably google it and find a catalogue somewhere on the internet which will give you the Kelvin ratings - it should have a make and the tube type at the end of the tube.

And in response to your LED question - we already can! They are made by a company called Solaris, they make LED luminaries however they are incredibly expenisve. But as I assume you meant affordable systems I would agree that in 2 to 3 years there should be affordable systems on the market as there will be more companies who utilise the technology.

Hope that helped!
Splatter.

Splatter got the Kelvin rating around the wrong way for the blue and white. Blue globes are up around the 15-20,000K.
Whites around 10-14,000K.
Pink are usually around 3-5,000K

T5s come in various wattages but it depends on how long the ones you want are. Generally the longer the tube, the higher the wattage. They also do standard output and high output (HO) tubes. The HO tubes run the higher wattage but need a different unit to operate in. It has a different ballast to the standard unit.
