Get quick answers to common questions about ATI Lighting

1. What makes ATI Straton LED pendants different from other aquarium lights?

ATI Straton LED pendants are designed with a large, flat panel of LEDs that distribute light evenly across the aquarium. Unlike many point-source LED fixtures, which can create hot spots and shading, the Straton uses built-in diffusers to ensure corals receive consistent PAR from edge to edge. The passive cooling system means the units run silently without fans, making them both efficient and discreet. Combined with German engineering and sleek design, ATI Straton lights are regarded as some of the most advanced reef lighting solutions available today.

2. Are ATI LED pendants suitable for SPS and demanding corals?

Yes, the ATI Straton Pro models in particular are built to deliver the high PAR levels that SPS corals require. With spectrum channels tuned to the crucial blue and violet wavelengths between 400 and 500 nm, the fixtures support strong photosynthesis in zooxanthellae algae, helping corals grow and display vibrant colour. The ability to customise the output through the ReefTech app also allows aquarists to fine-tune the light intensity and spectrum for different coral placements and species.

3. Can ATI lighting be controlled with an app?

ATI Straton LED pendants are fully controllable via the ReefTech app, which gives users the ability to adjust intensity, spectrum, ramping schedules, and even estimate PAR at various points in the aquarium. This makes it easy to simulate sunrise and sunset effects, create moonlight cycles, and build customised profiles that replicate natural reef conditions. App control is one of the standout features of ATI lighting, as it provides flexibility for both beginner aquarists and advanced reef keepers.

4. What sizes are available in the ATI Straton LED range?

The ATI Straton series is available in multiple sizes to suit different aquarium dimensions. Models such as the Straton Pro 102, 153, and 204 refer to their approximate coverage areas, allowing hobbyists to choose the fixture that best matches their tank footprint. This flexibility means ATI lighting can be used on nano reefs, mid-sized aquariums, and large SPS-dominated displays without sacrificing performance or coverage.

5. Are ATI lights energy-efficient compared to other brands?

ATI LED pendants are highly energy-efficient, with their passive cooling design reducing power consumption and eliminating the need for fans. By spreading the light more evenly, they make better use of each watt of output, ensuring that energy is directed toward coral health rather than wasted on excess heat. Many aquarists report lower power bills and longer fixture lifespans when switching to ATI, making them a cost-effective choice for long-term reef keeping.

6. Do ATI still make T5 tubes and hybrid fixtures?

Yes, ATI continues to produce its well-known T5 fluorescent tubes, including popular options such as Blue Plus, Coral Plus, Aquablue Special, and Purple Plus. These are often used in hybrid systems alongside LEDs to maximise spectrum and colour rendition. ATI also manufactures Powermodule hybrid fixtures, which combine LED panels with T5 technology in a single unit. This hybrid approach is particularly appealing to reef keepers who want the shimmer of LEDs with the proven growth benefits of T5.

7. How long do ATI LED pendants last?

ATI Straton LED pendants are designed to last for many years, with high-quality components and passive cooling reducing wear and tear. Unlike traditional T5 or metal halide systems that require regular bulb replacements, LEDs have a much longer lifespan. While output may slowly decline over time, most ATI fixtures continue to perform effectively for five to ten years depending on usage. This durability makes them a smart investment for serious aquarists.

8. Are ATI Straton lights noisy?

No, ATI Straton fixtures are completely silent. Unlike many other LED systems that use fans for active cooling, ATI pendants rely on a passive cooling design built into the fixture’s aluminium body. This ensures efficient heat dissipation without moving parts, resulting in zero fan noise and fewer maintenance issues. For aquarists who value a quiet living space or display area, this is a significant advantage.

9. Where can I buy ATI lighting in the UK?

ATI lighting products, including Straton LED pendants and T5 tubes, are available through authorised retailers in the UK. Charterhouse Aquatics stocks a full range of ATI lighting solutions, offering expert support, warranty coverage, and fast delivery. Purchasing from a trusted supplier ensures you receive genuine products and after-sales assistance if needed.

Their Straton LED pendants provide professional-grade performance with even light distribution, advanced spectrum control, energy efficiency, and silent operation. Whether you are keeping a mixed reef, an SPS-dominated display, or a hybrid setup, ATI lighting delivers the precision and reliability needed to achieve long-term coral growth and colour.
