[takaco]

i bought a PL from a seller at caroussell, I went home to test instead of daylight (white/yellowish) the light is blue in color, i tried calling the seller but he never answer.


Or it is normal that blue light equal PL?

On the light tube is there any marking?

[limz_777]

pl is those plug in type , just change the bulb ?

[PKB]

The light tube should have some indication. Maybe maybe color temp is too high, above 12,000K.

PL stands for Philips Lighting (the company that originally invented the type of light). PL currently refers to a certain type of connector.

PL light can have different types of color temperatures (from reddish (grow lights or to enhace red tones in fishes ) -> warm white -> cool white (daylight for planted tank) ->blue (actinic) ) depending on the purpose.
Bluish light is commonly used in both freshwater & more often in salt water tanks to simulate moon light and to bring out the florescence of corals.

Looks like you got a high color temperature or actinic blue light bulb... just change the bulb to a lower color temperature one, something around 6,500K.

If its 6,500k PL blubs it should be more towards yellowish white tone... not bluish. Maybe just check the info printed on the PL bulbs, there should be specs printed on the base of the bulbs.

Plants can still grow in bluish tone lighting... just that it looks wierd to anyone viewing it.

That's 65 watts (power consumption).

Actinic = blue light - typically a Color temperature between 14000k - 20000k.

For planted tank, you want white light - that's usually 6500k to 8000k Color temperature

Okay, based on your photos, the power consumption of the bulb is 65 watts (thats not the color temperature) and the color spec is actinic blue... so you basically got a blue light. I guess that light bulb was meant to be more for use on marine tanks.

If you want a more natural light tone, buy another replacement bulb that is labelled as 6,500K or listed as "cool daylight'". Those lights will be whiter in color and much more suitable for freshwater planted tanks.

You'll have to check at other LFS, or check at the larger aquarium stores like Seaview or Qian Hu, they might carry the correct sized PL bulbs for your lightset.

The alternative is to check at those lighting shops, see if they also have compatible light bulbs.
