Refugium Light- 9W Power Compact

[spreerider]

i have one of those on a 5g planted tank, i got mine as a desk lamp then replaced the tube with 6500K one,
i found mine flickered alot at first but as it aged it started up faster.
one thing to do is remove the bulb and then put it back in, sometimes a poor connection can cause the bulb to flicker more on a weak ballast.
