Exo Terra Natural Light (Repti Glo 2.0 Compact Fluorescent)

• 6700 K full-spectrum daylight – closely matches natural daylight colour temperature.
• CRI 98 – renders animal and plant colours accurately instead of washing them out.
• No UVB output – a visible-light and UVA lamp only; pair with a dedicated Exo Terra UVB100, UVB150 or UVB200 bulb for species that need UVB.
• Two wattages – 13 W and 25 W, to match smaller and larger terrariums.
• Supports live plants – full-spectrum output helps planted terrarium growth alongside your main UVB and heat lighting.

13 W suits smaller terrariums or where this bulb is supplementing a dedicated UVB and heat setup. 25 W suits larger enclosures, or where extra brightness helps live plants and viewing. Wattage changes brightness and coverage only – colour temperature and CRI are identical across both.

Suitable as general terrarium lighting for all species, particularly for planted terrariums, and as a supplementary low-UV lamp for snakes, amphibians and nocturnal animals. Not suitable as the sole lighting for reptiles that need UVB for calcium metabolism – most diurnal lizards, tortoises and many chelonians – which need a dedicated UVB tube or bulb running alongside it.

*Estimated at 12 hours a day, a typical daytime photoperiod, at an approximate 30c/kWh household tariff. Actual cost depends on your tariff and how many hours a day the bulb runs.

Exo Terra's "Restore The Rays" guidance recommends replacing compact fluorescent terrarium bulbs annually – light output fades gradually with age even before a bulb fails outright, so a bulb can look fine while performing noticeably worse than a fresh one.

220–240 V AU mains. Fit into a compact fluorescent terrarium fixture rated for the bulb's wattage, and keep it clear of misting or splashing water.

• A dedicated UVB100, UVB150 or UVB200 bulb, for species that need UVB
• An Exo Terra compact fluorescent light fixture rated for this wattage
• A separate basking heat lamp on its own thermostat

Is this the same bulb as the old Repti Glo 2.0?

It's sold under Exo Terra's newer "Natural Light" name. Exo Terra's current published spec for this wattage lists it as a non-UVB, full-spectrum daylight bulb rather than the low-UVB formulation some keepers remember from older Repti Glo 2.0 packaging. If your animal's UVB needs are being met by this bulb specifically, check with a UV meter rather than assuming.

Do I still need a separate UVB bulb?

Yes, for any species that needs UVB for calcium metabolism. This bulb supplies visible daylight and UVA, not UVB.

What's the difference between the 13 W and 25 W versions?

Brightness and coverage – the 25 W suits larger enclosures or where extra output helps live plants. Colour temperature and CRI are the same across both.

How often should I replace it?

Exo Terra recommends annual replacement for its compact fluorescent terrarium bulbs, since light output fades gradually with age.
