In general, a bigger aquarium lamp generates a more powerful and intense light compared to a smaller bulb. However, this is not always the case. A compact lamp, however small, can generate a strong light that is at par with light produced by its larger counterparts. If you have limited space in your aquarium for a big lamp but need a strong light source, you`re going to do great with the 65W 420NM Super Actinic Power Compact Bulb - Straight Pin, UVL from Pet Store.

This slim lamp is long and thin so it hardly takes up a noticeable area, but it`s quality can compete against bigger, very high-output lamps running on standard wattage. It`s pin structure is perfect for long, narrow aquariums wherein space can be a challenge. No worries, though. This lamp will fit right in without a problem. Once fitted to your tank, the lamp will produce the bright white light that your aquatic pets need in order to survive.

The 65W 420NM Super Actinic Power Compact Bulb - Straight Pin, UVL is actinic, so it means that its light has a slightly blue tinge to it. This tinge complements the natural coloring of fish and corals so you`ll end up with a more vibrant-looking aquarium.
