It features a dusk and dawn effect to mimic natural light cycles, ensuring a stress-free environment. With water-resistant end-caps and energy-efficient technology, this unit is both safe and eco-friendly, making it a must-have for any pet owner. ## Description Product Description The Exo Terra light cycle unit electronic dimming terrarium lamp controller, is an electronic ballast, a timer and a dusk - dawn simulator in one. The timer can be set for three lighting periods: 10, 12 or 14 hours. When a daytime cycle starts it will take about 30 minutes to bring the light output of the bulb to 100 percent, simulating a natural dawn period. At the end of each daytime cycle it will take again about 30 minutes to go from 100 percent light output to 0 percent, simulating a natural dusk period. This is less stressful for the animals and even stimulates breeding behaviour in many species of reptiles. It gives the animals time to retreat into their burrows or hiding places. The Exo Terra light cycle unit provides a flexible lighting solution for your terrarium. Just mount the electronic ballast housing near the terrarium and connect the fluorescent bulbs to the water-resistant end caps. The long, flexible end-cap leads allow you to position the fluorescent bulbs very close to the animals, necessary when UVB bulbs are used (i.e.: Repti Glo 5.0 and 10.0). The long end-cap leads also provide the versatility to mount bulbs over any type of terrarium, regardless of size.

Instructions were not very detailed. I purchased with idea of just using one bulb but you actually need two to make it function. However you don't need to use repti glo bulbs so I just used a house hold bulb for the second light unit to save the expensive repti glo bulbs ### ⭐⭐ 2.0 out of 5 stars good idea but timer is unreliable *by R***D on Reviewed in the United Kingdom on 23 July 2014* The first unit I received always lost its cycle timing and eventually stopped working all together five months after use. Amazon were very quick at replacing next day. The scond unit only worked on cycle test mode so I had to manually switch on and off every day so really was no diffrent to to a standard light unit. Amazon wouldn't replace unit so gave a full refund. The idea of the light cycle unit is good but out of the two units this feature did not work. Very disappointed. ### ⭐⭐⭐⭐ 4.0 out of 5 stars seems a bit over priced for just the unit but it's amazing quality feels really sturdy and looks/feels it would last ... *by A***N on Reviewed in the United Kingdom on 19 May 2015* wasn't aware it didn't come with the uv light strips, seems a bit over priced for just the unit but it's amazing quality feels really sturdy and looks/feels it would last years --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/75263383-exo-terra-light-cycle-unit-40-watt-2-pieces](https://www.desertcart.sk/products/75263383-exo-terra-light-cycle-unit-40-watt-2-pieces) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-07-06*
