ExoRepti Deep Heat Projector Reptile Heat Lamp Bulb DHP 75W PAR30, Basking Light for Bearded Dragon and Leopard Gecko Review (2026)

Updated September 21, 2026 · Research-based review

Our verdict

ExoRepti's 75 watt PAR30 deep heat projector is a mid-power, light-free basking bulb sized for medium enclosures housing bearded dragons and leopard geckos. Its carbon fiber filament design runs light-free heat, but the large PAR30 face may not fit shallow dome fixtures, so checking fixture compatibility first is worth the extra minute.

What we liked

  • + 75W is a practical middle option for mid-size enclosures
  • + PAR30 reflector shape keeps the heat beam directed downward
  • + Infrared warmth without bright light suits leopard geckos

Trade-offs

  • - Large PAR30 face may not fit shallow or small domes
  • - Always pair with a dimming thermostat for a stable basking area

A middle wattage option

At 75 watts, this ExoRepti bulb sits between the brand's lower 55 watt version and higher 100 watt option, giving keepers a middle ground for enclosures that need more heat than a small setup requires but less intensity than a large tank demands. The listing specifies a PAR30 reflector shape with an E26 or E27 base, roughly 3.8 by 3.8 by 4.7 inches in size, built with a carbon fiber filament and metal aluminum housing that the manufacturer describes as waterproof and explosion-proof rated. That build is aimed at standing up to the humidity many reptile enclosures run, particularly for species that need higher ambient moisture alongside a basking heat source.

Carbon infrared heat without light

Like other deep heat projectors, this bulb is built to heat up quickly and produce infrared warmth without emitting visible light, which the listing frames as ideal for diurnal reptiles that bask to thermoregulate, covering bearded dragons, leopard geckos, tortoises, snakes and several other species. Because there is no light output, the bulb can run overnight as a heat source without interfering with a reptile's normal day and night light cycle, which is one of the more common reasons keepers choose a DHP bulb over a standard incandescent basking bulb for round the clock heat needs.

Fixture size and fit

A PAR30 bulb has a noticeably wider face than a standard incandescent basking bulb, and the listing's own dimensions put the bulb at nearly 4 inches across, which will not fit inside smaller or shallow dome fixtures designed around standard bulb shapes. Before buying, checking that the current dome fixture, or a new one being purchased alongside it, is rated for PAR30 bulbs and has enough interior depth and ventilation clearance is a necessary step, since forcing a PAR30 bulb into an undersized dome risks overheating the fixture itself rather than just the enclosure air.

Pairing with a thermostat

The product page includes a safety note warning against touching the bulb directly due to high surface temperature, which reflects how much heat a deep heat projector concentrates compared to a standard bulb of similar wattage. As with other DHP bulbs, there is no built-in temperature regulation, so running it through a dimming or proportional thermostat with a probe placed at the basking surface is the safer approach for keeping a stable, species-appropriate temperature rather than relying on the bulb's wattage alone to estimate heat output. This matters especially for leopard geckos, a smaller bodied species where overheating risk is higher than with a large bearded dragon or tortoise.

Who this wattage suits

The 75 watt version is a reasonable starting point for medium sized enclosures, roughly in the 20 to 40 gallon range, housing bearded dragons or leopard geckos that need dependable basking heat without the higher output of the brand's 100 watt bulb. Keepers with larger enclosures or species needing more intense heat should look at ExoRepti's 100 watt version instead, while those with very small tanks may find even 75 watts runs hotter than needed unless mounted with extra height and thermostat control. Confirming fixture compatibility and planning for a thermostat purchase are the two most important steps before this bulb arrives, and keeping a spare standard basking bulb on hand is also worth it in case the enclosure needs visible daytime light in addition to this light-free heat source.

Frequently asked questions

Will this bulb fit a standard dome fixture?

Not always; the PAR30 shape is wider than a standard incandescent bulb, so checking that the dome fixture is rated for PAR30 bulbs and has enough clearance is important before buying.

Does this bulb emit visible light?

No, it is a deep heat projector designed to produce infrared heat without visible light, so it can run continuously without disrupting a reptile's day and night cycle.

What reptiles is the 75 watt version suited for?

The listing markets it for bearded dragons and leopard geckos in medium sized enclosures, sitting between the brand's lower and higher wattage DHP options.

Do I need a thermostat with this bulb?

Yes, since it has no built-in temperature limiter, pairing it with a thermostat and probe at the basking spot is the safer way to maintain a stable temperature.
