# Exo Terra PT2057 Dome Light Fixture

Exo Terra PT2057 is a compact dome light fixture for terrariums, with a polished aluminium reflector, ceramic socket and on/off switch. The listing claims the reflector can increase UVB output by up to 100%, but does not establish that as an independently verified result. Bulbs are not confirmed as included, and the listed wattage details conflict.

## At a glance

- Deep, polished dome reflector made from aluminium, according to the listing.
- Ceramic socket is stated to accommodate compact fluorescent or incandescent bulbs.
- The listed features include an on/off switch and a 180cm power cord.
- The manufacturer claims the reflector increases UVB output by up to 100%. This is a claim, not a verified measurement.

## Pros

- The reflective dome and ceramic socket make this a fixture option for buyers choosing compatible terrarium lighting.
- An on/off switch is listed, so the fixture has a stated local control.

## Before you buy

- The listing is inconsistent about wattage: the title says 150W, while a details entry says 75 watts. The 120 Volts claim and AC adapter description are also not reconciled for a UK listing. Confirm the intended electrical specification and bulb compatibility before buying. Bulb inclusion is unconfirmed, and the stated up-to-100% UVB increase is a manufacturer claim rather than an independently established result.

## A good fit for

- Terrarium keepers looking for a dome fixture with a reflective aluminium shade and ceramic socket.
- Buyers who already know which compatible bulb type and electrical configuration they need.

## Less suited to

- Anyone needing a confirmed bulb included in the package.
- Buyers who require settled wattage or UK electrical specifications without first resolving the listing discrepancies.

## Customer feedback

The supplied evidence contains aggregate ratings but no written customer-feedback summary. The rating distribution is mostly five-star, with smaller lower-star groups, but it cannot show what customers liked or disliked or identify reasons. It therefore offers limited guidance about fit, bulb compatibility or the conflicting electrical details.

## Frequently asked questions

### Does the fixture include a bulb?
The supplied listing does not confirm a bulb is included, so check the selected listing before purchase.
### What wattage is the Exo Terra PT2057?
The listing conflicts: its title says 150W, while a details entry gives 75 watts. Confirm the correct rating before choosing a bulb or connecting it.
### What bulb types are listed as compatible?
The listing names CFL, fluorescent and incandescent bulbs, and describes a ceramic socket for compact fluorescent or incandescent bulbs. Confirm the specific bulb’s fit and electrical requirements.
### Is the UVB increase guaranteed?
No. The listing claims up to 100% more UVB output from the reflector, but provides no independent verification or measurement conditions.
