Coralife T5HO Actinic Aquarium Lamp

The Coralife T5 bulbs are super versatile! They'll fit any T5 fixture as long as you use bulbs with the same wattage as the ones currently in your fixture. T5 bulbs come in two main types: HO bulbs (available in 24W, 31W, 39W, or 54W) and NOs (9W, 14W, 21W, or 28W). These bulbs have a diameter of 5/8' or .625'. The size of this particular bulb is 30'.

Using your Coralife T5HO Actinic Aquarium Lamp is easy. First, make sure your T5 fixture is turned off. Check the wattage of the bulbs already in the fixture and replace them with Coralife T5 bulbs of the same wattage. Simply insert the new 30' bulb into the fixture. When handling the bulb, it's a good idea to wear gloves to avoid getting fingerprints on it, as this can affect the bulb's performance. Keep the fixture clean to ensure the best lighting for your aquarium. If the bulb starts to flicker or dim, it's time to replace it. And always store extra bulbs in a cool, dry place.
