Zoo Med ReptiSun T5 HO Terrarium Hood with 10.0 Bulb, 24 inch L Review (2026)

Who this hood suits

This 24 inch ReptiSun hood is built for keepers setting up a mid-size enclosure for a desert species such as a bearded dragon, where a strong, evenly spread UVB source across a longer basking zone matters more than a single spot bulb. Because it ships with the 10.0 bulb already included, it removes a common first-timer mistake of buying a hood and a bulb separately that turn out to be mismatched in length or wattage. The hood houses a single T5 HO lamp using an energy efficient electronic ballast for a fast, reliable start rather than the flicker and slow warm up of older fluorescent starters. Keepers with a smaller or larger tank should check the length carefully, since Zoo Med sells this same hood in several sizes and 24 inches will not fit every enclosure.

Specs and what is in the box

The fixture measures about 27.75 inches wide by 6 inches deep and roughly 1.5 inches tall, weighing about 2.1 pounds, with a low profile design intended to sit unobtrusively on top of a screen lid. Inside, it holds a 24 watt, 22 inch ReptiSun T5 HO 10.0 bulb, the same tube family reviewed on its own elsewhere in this lineup, so the UVB performance and eventual replacement schedule match that standalone bulb. A highly polished, curved reflector lines the interior of the hood, which is designed to direct more of the UVB, UVA and visible light produced by the tube down into the enclosure rather than losing it upward and to the sides. Zoo Med backs the hood with a 1 year warranty against manufacturing defects.

Setup and ongoing care

Setup is largely plug and play since the bulb arrives pre-installed or matched to the hood, so keepers mainly need to set the hood on a secure screen lid and confirm the mounting height matches Zoo Med's published distance chart for the 10.0 bulb rating. Because the fixture is described as low profile at only about an inch tall, it is a reasonable fit for stands or shelving with limited clearance above the enclosure, unlike bulkier dome style fixtures. As with any UVB tube, the included 10.0 bulb will lose meaningful UVB output over months of use well before it stops producing visible light, so plan on budgeting for a replacement tube on a routine schedule rather than assuming the bulb is fine as long as it still glows.

Trade-offs and how it compares

Against the Arcadia T5 UVB fixture kit at a similar 22.5 inch length, which holds a notably higher independent score in this category, the Arcadia kit ships with a 12 percent UVB desert rated tube aimed at the same class of animal, and the two are close competitors for a bearded dragon style setup. Compared with buying the plain Zoo Med 24 inch hood and the 10.0 bulb as two separate purchases, this combo is the more convenient route for a first setup, though experienced keepers restocking a hood they already own with a fresh tube will naturally buy the bulb alone. The site's own cons note that a strong 10.0 tube is more output than shade dwelling species need, so this hood is squarely built for desert species rather than a general purpose fixture.

Bottom line

For a first time desert species setup around 24 inches long, this hood and bulb combo earns its our score of 8.9 out of 10 by pairing a matched, tested fixture and tube so the keeper does not have to guess at compatibility. It is a strong fit for bearded dragons and similar UVB hungry species, and a poor fit for shade dwelling animals that would be overexposed by a 10.0 rated tube. Replace the included bulb on the same schedule recommended for any T5 HO UVB tube, generally within about a year of daily use, even though the fixture itself should last considerably longer.
