FAQ: Frequently Asked Questions
Q: What are LEDs?
A: Light Emitting Diode is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device. When spaced appropriately, the LEDs provide better coverage than an HPS bulb and generate much less heat and can be adjusted to suit any grow space.
Insun use primarily high efficacy warm white diodes as they most closely mimic the spectral output of the sun, providing bright white light in all wavelengths between 400-800 nm. This gives the energy required for all the plant’s seasonal requirements.
Certain light models and PCBs are enhanced with discrete colour diodes to promote enhanced flowering and production of valuable flavours and increased development of valuable phyto-compounds.
Q: What is the right light for full cycle: vegetative and flowering/bloom?
A: All of our lights are designed for full cycle usage, meaning you need only one light for seed/clone/seedling to harvest. The operating height and power output will vary according to the stage of growing you are currently in.
Most customers choose the QUADRA 200 for full cycle usage. This model produces a high quality full spectrum white light that promotes healthy growth at all stages of the plant lifecycle, whether in vegetative growth or flowering.
Please contact us with any questions regarding the best configuration for your growing needs.
Q: How do I select the right wattage for my coverage area?
A: The amount of wattage you select for your coverage area for flowering/full cycle usage is going to be based on it's ability to generate PPFD values of 900-1000 µmol/m²s. Here is a list of typical coverage areas and recommended wattages:
0.6m x 0.6m - 200 Watts
0.9m x 0.9m - 300 Watts
1.2m x 1.2m - 400-800 Watts
For vegetative growth only, PPFD needs are about half that of flowering (roughly 500 µmol/m²s) which means you will need half as much wattage as you would for full cycle/flowering use.
Q: Do I have to assemble the lights?
A: All insun lights come fully assembled except for LINEA, which requires you to mount the power supply on top with the provided screws. PROPA 60 & PROPA 80 with herb garden option can come with a flatpack plywood stand that requires assembly; instructions are included.
Q: Do you ship discreetly?
A: Yes, all of our lights ship in plain brown packaging and make no reference to "grow lights". The return label simply says "insun" and our return address.
Q: What is your order lead time?
A: Lights are built to each customer’s order. Allow up to 3 weeks for orders to be completed. Please contact us and we will be happy to let you know our current build lead times.
Q: What is your warranty?
A: We offer a 1 year warranty on all components. Additionally, the power supplies we use in all of our products come with a 2 year manufacturer warranty.
Q: How much is shipping?
A: All shipping charges are calculated at checkout. International shipping is available by DHL International Mail - please contact us direct at insun@setek.co.nz for shipping quotes.
Q: How high above the plants should I hang my QUADRA 200 light?
A: For best results the QUADRA 200 should be between 300mm to 600mm above the canopy and to achieve optimal PPFD across the plant canopy, multiple QUADRA 200s should be used for edge to edge coverage (one luminaire per 600mm x 600mm square). Refer to the PPFD maps to determine the right height for your space.
Q: Where are your fixtures made?
A: Our grow lights are engineered and built in Taupo by our engineers from locally manufactured and imported parts and materials.
Q: Why LED vs HPS?
A: Higher efficiency with far less waste heat means more light for less power, and minimal fire risk compared to inferior and obsolete HID lighting.
Far superior light spectrum from white LEDs provides the plant with balanced light much closer to the sunlight which plants evolved under, as opposed to the orange and infrared dominant output spectrum of HPS.
Larger light emission surface means a more even light distribution blanketing the canopy, and the plants are also not as prone to hot spots and heat stress as they are under HPS, which acts as a very intense point source of light.
Plants simply grow healthier, thicker, faster, and better under LED, able to express their full genetic potential without suffering weird photomorphogenic effects such as stretching which occurs under the unbalanced spectrum of HPS.
This all translates to increased yields, improved quality, and tastier and more fragrant harvests of healthy fruit and flowers.
Q: What is the importance of a heat management?
A: Heat is the main enemy of LEDs. Insufficient cooling can lead to diminished brightness and premature product failure. insun lights are sufficiently heatsinked to maintain a thermal junction temperature well below that recommended by the LED manufacturers.
Q: What if I do not see the product that I want listed on your website?
A: We do custom builds all the time. Please contact us, and we would be happy to assist with a custom solution!
