No replacement schedule given for this one

Exo Terra's smaller bulbs in this range carry an explicit note that UVB output fades well before the tube stops glowing, so replacement should follow a schedule rather than how bright it looks. That guidance is not printed on this bulb's own card, so treat it as sensible here too rather than assuming it lasts indefinitely.

Why we chose it

The 34-inch length is what earns this a place over the shorter bulbs in the range: it covers a bigger vivarium in one tube rather than needing two shorter ones end to end. A mid-strength UVB output like this also suits more species than a top-end desert bulb does.

Full description

Not every reptile that basks does it the way a bearded dragon does, and a 34-inch tube putting out a moderate 7% UVB is built for the ones in between: baskers, not full-sun desert species.

It is a T5 Very High Output tube with Exo Terra's Sunergy phosphor blend, engineered in Germany, putting out 7% UVB aligned with Ferguson Zone 2 and the Mesophotic Zone. That covers reptiles that spend only part of their time in direct sunlight rather than baking under it all day. It fits standard T5 fluorescent fixtures and the Exo Terra T5 Terrarium Top.

For reptiles that bask occasionally rather than constantly

For reptile, amphibian and invertebrate use only

Who it's for: keepers of reptiles that use a basking spot some of the time rather than living under full desert sun - Zone 2, Mesophotic-zone species is the target here, not Zone 4 desert baskers.
