We use Cree CXB3590, Citizen CLU048 and Vero29 COBs exclusively as they most closely mimic the spectral output of the McCree Spectrum. Providing bright white light in all wavelengths between 400-800 nM, instead of just at the Chlorophyll A&B peaks as in red and blue LED fixtures, gives the energy required for all the plant's physiological responses. Q: What is the difference between the Citizen CLU048, Cree CXB3590. A: We offer lights using Cree, Citizen With respect to efficacy and efficient output, these are very similar. There are a few differences worth noting.
Cree does binning - Citizen do not. Binning is a method of categorizing LEDs by light output (lumens) at the time of manufacturing. We only use top BIN Cree CXB3590 (CD/DB bin) LEDs. Although the Citizen CLU048 COB is physically smaller than the CXB3590 COB it's electrical characteristics as well as spectral distribution is very similar to the CXB3590.
Q: What is the right light for full cycle, vegetative and flowering? A: All of our lights, unless denoted, are designed for full cycle usage. The operating height and power output will vary according to the stage of growing you are currently in. We recommend 3500K for full cycle usage (generally) and 4000K - 5000K for vegetative growing only. We also offer a color temperature for flowering only.
Q: What color temperature should I choose? A: Most customers choose the 3500K color temperature for full cycle usage (both vegetative as well as bloom/flowering). The 3500K color spectrum has a good amount of both blue spectral output (400-450 nM for vegetative growth) as well as red spectral output (600-660 nM for flowering). For flowering/bloom only, most growers opt for 3000K as it has a more pronounced red spectral peak with slightly less blue spectral output, mimicking more closely the autumnal sun spectrum. 4000K and 5000K are good for vegging and also has many applications well suited for young plants.Q: How do I select the right wattage for my coverage area? Here is a list of typical coverage areas and recommended COB/Mid Power Diode wattages. Q: Can I mix color temps? We can customize any light to include the color temps of your choice. If you have specific needs let us know - our COB LEDs are available in 3000K, 3500K, 4000K, 5000K and 6500K color temps. You are welcome to mix and match color temperatures as well - there is no additional charge. Leave me message for customized temps, MOQ: 2pcs at least. Q: Do I need a separate light for veg and a separate light for flowering/bloom? A: No, most of our lights (unless denoted) are for full cycle usage, meaning you need only one light for seed/clone/seedling to harvest.
We use LEDs which output a very bright white and offer color temperatures designed to mimic those of natural sunlight. Q: Why LED vs HPS? A: LEDs compete with traditional HPS and Metal Halide HID lighting sources in a number of ways, including greater energy efficiency, longer lifetime, and smaller size. They, however, are more expensive.
LEDs operate at a much lower temperature so there are less cooling requirements (energy, noisy a/c and fans) - also, because they put out less radiant heat they can be positioned closer to the plant canopy. The ability to configure LEDs also helps to increase their usability over HPS, which traditionally must be positioned higher - and directly above - the canopy. LEDs can be placed in different configurations above the canopy to suit many different sized growing areas. Q: Why is cooling important with LED Grow Lights - how can I make my lights perform better? A: We use a passively cooled design that manages safe operating temperatures without the aid of forced air induction by fans.Maintaining airflow across the pins of the heat sinks aids in dissipating the maximum amount of heat as it speeds up the interchange of hot and cool air. We highly recommend using a clip on oscillating fan or other such fan in order to maintain a slow steady airflow across the heat sinks as this has been shown to lower the heat sink ambient temperature and will also aid in increasing our light's efficiency, and ultimately, PAR output. Q: What is the importance of a well engineered heatsink? A: Heat is the main enemy of LEDs. Insufficient cooling can lead to diminished brightness and premature product failure. Designed specifically around the Cree CXB3590 and CITIZEN Clu048 series, these heat sinks maintain temperature well below that recommended by the LED manufacturers.
These special engineered pin cushion heat sinks are anodized single piece extruded aluminum, increasing the heat dissipation effectivity. Pin cushion designs help to provide more surface area for better cooling.
