The DHP throws infrared A and B with almost no visible light, so it can run 24 hours a day without disturbing a nocturnal photoperiod. The halogen adds a bright, warm-white basking pool for the hours the enclosure is lit. Together they cover the two heat jobs most reptile keepers end up buying separately - background warmth and a daytime hot spot - from one order.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e50 W Deep Heat Projector\u003c\/strong\u003e - infrared A and B heat with virtually no visible light output, so it can stay on through the night without acting as a light source.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e75 W PAR30 halogen basking lamp\u003c\/strong\u003e - a warm ~2,750-2,800 K spot for the daytime basking zone, on a frosted lens that spreads the beam rather than a tight hot circle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoth on E27\u003c\/strong\u003e - drop-in replacements for standard ceramic E27 fixtures; no proprietary fitting to source.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe 50 W DHP can outperform a 100 W ceramic heat emitter\u003c\/strong\u003e at the basking point, according to Arcadia, because the internal reflector focuses more of the output forward instead of losing it sideways and backward.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo heat sources, two jobs\u003c\/strong\u003e - the DHP holds background temperature and night-time warmth, the halogen supplies the bright daytime basking spot baskers actually orient to.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eContents\u003c\/th\u003e\n\u003ctd\u003e1x Arcadia Deep Heat Projector 50 W, 1x Arcadia Halogen Basking Spot 75 W PAR30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFitting\u003c\/th\u003e\n\u003ctd\u003eE27, both lamps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVoltage\u003c\/th\u003e\n\u003ctd\u003e230-240 V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDHP visible light output\u003c\/th\u003e\n\u003ctd\u003eVirtually none - infrared A\/B only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHalogen colour temperature\u003c\/th\u003e\n\u003ctd\u003eApproximately 2,750-2,800 K (warm white)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHalogen UV output\u003c\/th\u003e\n\u003ctd\u003eNone - heat and visible light only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHalogen construction\u003c\/th\u003e\n\u003ctd\u003eHard glass, splash resistant, internal metal reflector, frosted lens\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eThermostat requirement\u003c\/th\u003e\n\u003ctd\u003eDimming thermostat, one per lamp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003eBA9193\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhich lamp is doing which job?\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eLamp\u003c\/th\u003e\n\u003cth\u003eVisible light\u003c\/th\u003e\n\u003cth\u003eBest use\u003c\/th\u003e\n\u003cth\u003eTypical run time\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e50 W Deep Heat Projector\u003c\/td\u003e\n\u003ctd\u003eVirtually none\u003c\/td\u003e\n\u003ctd\u003eBackground and night heat, ambient temperature support\u003c\/td\u003e\n\u003ctd\u003eUp to 24 hours, on a dimming thermostat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e75 W PAR30 Halogen Basking Spot\u003c\/td\u003e\n\u003ctd\u003eBright, warm white\u003c\/td\u003e\n\u003ctd\u003eDaytime basking hot spot\u003c\/td\u003e\n\u003ctd\u003ePhotoperiod hours only, on its own dimming thermostat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThey are not interchangeable.
