SPECTRA boasts 3 new features that are coral-friendly

SPECTRA has 3 new features that are coral friendly! Coral Stress!

Coral-friendly 1. Reef Depth Spectrum of SPECTRA

Reef Depth Spectrum

Since SPECTRA comes pre-installed with these reef depth spectra from 0-30m, you can easily specify that depth spectra by selecting the depth at which the coral was inhabited.

That alone is enough for coral photosynthesis and easily provides the right light environment.

On top of that, "I want to make the color more beautiful!" determine whether that color is fluorescent protein or chromoprotein, and then arrange the default depth spectrum appropriately.
Example) CFP(Cyan fluorescent protein) → Increase the UV/Violet channel by 10-20%.
Example) BFP(Blue fluorescent protein) → Increase the UV/Violet channel by 20-30%.

Reef Depth Spectrum | APP screen

Yes, SPECTRA reef depth spectrum allows us to customize the wavelength intensity to suit the desired corals color.

In addition, SPECTRA depth spectrum is equipped with a mechanism that automatically preserves the blue-band (400-500nm) wavelength intensity common to all depths, so that the amount of light in the deep field does not exceed the amount of light in the shallow field.

This is the first care function for the coral-friendly SPECTRA.

* Avoid extreme wavelength intensity, as excessive wavelength intensity can cause photoinhibition and bleaching.

SPECTRA dimming is not lost

SPECTRA's depth spectrum is aquarist-friendly.
SPECTRA has two dimming systems, "Simple Dimmer (based on depth)" and "Expert Dimmer (for professionals)", but unless you are familiar with coral pigments, you won't know what wavelengths to use and which intensity to use, and the same is true for other lights.
In this regard, SPECTRA can first set a rough depth of water with simple dimming and then arrange it appropriately with expert dimming to achieve the optimal light environment without any hesitation.

Coral-friendly 2. SPECTRA V-beam reflector

V-beam reflector

SPECTRA has succeeded in the original development of an optical reflector that has an infinitely flat light intensity distribution with less light intensity loss than conventional optical lens systems. It is called "V-beam reflector".

Its characteristics are exactly like a T5 fluorescent lamp, and the inherent contrast difference between light and dark LED has been largely eliminated.

For example, take a look at the graph below. The left is the light intensity distribution of the old KR93SP and the right is the SPECTRA. You can see that the light intensity distribution of the third row of 60cm (purple) has been improved to infinitely flat.

* In fact the light distribution from a depth of water shallower than "60cm" will be uniform because of the reflections obtained on the glass surface.

PPFD distribution comparison image with ordinary LED light

First of all, the light reaches every corner of the tank by using the reflection of the tank's glass surface to illuminate every part of the tank evenly, and the light hits the sides and front of the coral, promoting beautiful pigmentation throughout the coral.
Secondly, because strong light is not concentrated directly underneath the lighting, coral does not suffer from light inhibition, bleaching, or other "burn" phenomena, even if the coral is placed directly underneath the lighting.

This is the second care function for the coral-friendly SPECTRA.

* On the other hand, the whole tank will be brighter, so you may need to be creative about where to place the LPS.

Coral-friendly 3. SPECTRA's Lunar cycle function

Lunar function run intensity

SPECTRA also paid a lot of attention to lunar ray.

What a great way to reproduce the brightness of realistic lunar ray!

During normal operation, SPECTRA is controlled as a "percentage (0-100%)", but during moonlighting it is controlled as a "basis point (0.00-100.00%)" (a second decimal place is also displayed on the LCD panel).
This mechanism allows the correct lunar ray spectrum to be illuminated even with a faint lunar ray setting of 1 lux brightness.

This is the third care function for the coral-friendly SPECTRA.

* The depth spectrum of your choice can be assigned to the lunar spectrum.

Add VitalWaveII UVA370 to SPECTRA becomes full sunlight!

In addition, by adding a UVA 370nm wavelength to SPECTRA, full-spectrum sunlight, which also covers UV rays, can be reproduced. The 400-700nm range of visible light is assigned to SPECTRA, and the 350-400nm UVA region is assigned to VitalVaveII UVA370. This makes it possible to meet the light requirements of all photosynthetic organisms at a high level, not only terrestrial plants, but also aquatic plants, sea grasses and corals.

The UVA region is a wavelength that has a significant impact on pigmentation mainly as a UV defense, promoting redness, such as anthocyanin in terrestrial plants and fluorescent protein and pigmentation responses in corals.

Other Features

Thunder Scheduling Function

Thunder Scheduling Example

The thunder scheduling feature has three presets, each of which can be configured with an interval of occurrence, time of occurrence, and number of flashes, so that complex lightning effects can be reproduced when used together.

* The thunder spectrum can be assigned to the depth spectrum of your choice.

Function to connect via router

Example connection via router

If you use your home WiFi router, you can control up to 10 units SPECTRA from your smartphone. Also, since it is via the router, you can operate it while you are on the Internet.

* Please use the 2.4GHz band as the 5GHz band is not supported.

WiFi synchronization function

WiFi synchronization function

Even if you don't have a WiFi router at home, SPECTRA can synchronize 1 parent device(Master) with 4 children(Slave *including smartphones) via WiFi communication.

* If you want to operate with 2 smartphones, you can operate up to 2 SPECTRA.
* Just by setting the dependency, that unit becomes a child(Slave) that synchronizes with the parent(Master).

Variable drive function

Variable drive function

It is possible to increase or decrease the brightness of the entire lighting in three levels without changing the already set program. For example, if you change the installation height of the light, you would normally have to change all the dimmers for each stage of the auto setting, but use the variable drive function, you can switch the product's power consumption to 70W mode, 140W mode, and 200W mode.

Equipped with two large 95mm FANs & Removable FAN Cover

Equipped with two large 95mm FANs & Removable FAN Cover

Since the power consumption of the SPECTRA is up to 200W, two large 95mm fans are installed to ensure both airflow and quietness. Also, the fans do not rotate constantly, but instead monitor the heat sink temperature and activate it when it exceeds 35 degrees. In addition, the fan cover is detachable so that it can be washed in water when cleaning dust from the fan.
