It's sold in 50W (RARHP50) and 80W (RARHP80) versions on an E27 fitting, with published temperatures from 150mm out to 400mm so you can position it against a real target temperature rather than a guess.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInfrared-A and infrared-B output\u003c\/strong\u003e — heat that reaches deeper into tissue than a standard basking bulb, closer to how radiant heat behaves in the wild.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVirtually no visible light\u003c\/strong\u003e — safe to run overnight without disturbing an animal's day-night cycle, unlike a basking spot bulb.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePublished temperature-by-distance table\u003c\/strong\u003e — Arcadia states actual °C figures at four distances for both wattages, not a single headline number.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide, flood-style beam\u003c\/strong\u003e — described by Arcadia as a wider, safer spread rather than a tight hot spot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficient for its output\u003c\/strong\u003e — Arcadia states the 80W model can outperform a 100W ceramic heat emitter or tungsten lamp for delivered warmth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard E27 fitting\u003c\/strong\u003e — runs in a standard dome or clamp fixture rated for the wattage, no special ballast needed.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich wattage do I need?\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eDistance to animal\u003c\/th\u003e\n\u003cth\u003e50W (RARHP50)\u003c\/th\u003e\n\u003cth\u003e80W (RARHP80)\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e150mm (6\")\u003c\/td\u003e\n\u003ctd\u003e55°C\u003c\/td\u003e\n\u003ctd\u003e62°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e200mm (8\")\u003c\/td\u003e\n\u003ctd\u003e45°C\u003c\/td\u003e\n\u003ctd\u003e51°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e300mm (12\")\u003c\/td\u003e\n\u003ctd\u003e36°C\u003c\/td\u003e\n\u003ctd\u003e44°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e400mm (16\")\u003c\/td\u003e\n\u003ctd\u003e29°C\u003c\/td\u003e\n\u003ctd\u003e36°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003eThese are Arcadia's own measured figures, not ambient-adjusted for every room — actual surface temperature will run warmer on a hot day and cooler on a cold one. Use the table to choose a wattage and a starting distance, then fine-tune with a thermometer.\u003c\/p\u003e\n\u003cp\u003eAs a rule of thumb: the 50W suits smaller enclosures and species with a lower target basking temperature, and the 80W suits larger enclosures or animals such as bearded dragons and monitors that need a hotter basking zone. Both can be mounted further away and dropped closer if the reading falls short.\u003c\/p\u003e\n\n\u003ch3\u003eSafety and thermostat requirement\u003c\/h3\u003e\n\u003cp\u003eArcadia's own instruction is that this lamp should always be run through a thermostat, and specifically a dimming thermostat for accurate control of the thermal gradient — an on\/off thermostat is not the right match for a lamp like this. Check the actual surface or basking-spot temperature with a non-contact infrared thermometer rather than relying on the table above alone, since enclosure ventilation, ambient room temperature and reflector type all shift the real-world result. A guard is recommended wherever the animal, decor or its tail can make contact with the fixture.\u003c\/p\u003e\n\n\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSuitable for:\u003c\/strong\u003e reptiles and amphibians that need a genuine basking heat source, run alongside a UVB lamp rather than in place of one — the Deep Heat Projector supplies heat only, not UV.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e use without a thermostat, use as the sole source of UVB (it has none), or mounting where an animal can climb onto or directly contact the fixture.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cp\u003eThe lamp only.

Whatever that term is, it applies in addition to your rights under the Australian Consumer Law, which are not reduced by any manufacturer policy. This is a mains-powered item — 220-240V, 50Hz on an E27 fitting for the Australian market. Standard freight applies.\u003c\/p\u003e\n\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\u003ch4\u003eDo I need a thermostat with this lamp?\u003c\/h4\u003e\n\u003cp\u003eYes, always. Arcadia specifies a dimming thermostat for accurate control of the thermal gradient — running it without one risks overheating the basking zone, since the lamp has no built-in temperature limiting.\u003c\/p\u003e\n\u003ch4\u003eDoes the Deep Heat Projector give off any UVB?\u003c\/h4\u003e\n\u003cp\u003eNo. It is a heat-only lamp using infrared-A and infrared-B wavelengths. Run it alongside a separate UVB lamp such as Arcadia's ProT5 or D3 compact range for a complete setup.\u003c\/p\u003e\n\u003ch4\u003eShould I choose the 50W or the 80W?\u003c\/h4\u003e\n\u003cp\u003eMatch it to your enclosure size and target temperature using the table above. At 300mm the 50W reads 36°C and the 80W reads 44°C — if your species needs a hotter basking spot or your enclosure is larger, the 80W gives more headroom.\u003c\/p\u003e\n\u003ch4\u003eCan I run it overnight?\u003c\/h4\u003e\n\u003cp\u003eYes. It produces virtually no visible light, so many keepers use it for a 24-hour thermal gradient on species that need warmth around the clock without a light source disrupting their day-night cycle.\u003c\/p\u003e\n\u003ch4\u003eWill it disturb my animal's day-night cycle like a basking bulb does?\u003c\/h4\u003e\n\u003cp\u003eNo — that's the point of the design. Because it emits effectively no visible light, it can stay on overnight without acting as a second \"daytime\" light source.\u003c\/p\u003e","brand":"Arcadia","offers":[{"title":"50w","offer_id":55335324025123,"sku":"AA3103","price":69.95,"currency_code":"AUD","in_stock":true},{"title":"80w","offer_id":55335404339491,"sku":"AA3104","price":76.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/MF55441.jpg?v=1786073275","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/arcadia-deep-heat-projector","provider":"Nicks AOT","version":"1.0","type":"link"}
