T5 light yellowish

[blackjack0512]

Hi,

Just to check with anyone...my half yr old 3 ft T5 light seem to be yellowish instead of white as compared to my 2ft e-ballast PL lamp.

I know HDB void deck r using T5 light tubes and they are all yellowish too...so it is true that T5 light are yelloish one?

not true... 6500k is yellowish but not like those HDB block light.... its more like white with yellow tint for the 6500k bulb... if thats the best for plant growth.. if you want whiter bulb can go for higher K... me using 10k bulb..

but those after 10k will be more towards the blue side... those are more suitable for marine tanks...
