Platinum LED use a a combination of differently colored LEDs (12 different color wavelengths in all) to create a. Full-spectrum light that is specifically tuned for all stages of plant growth.
Platinum lights and cheaper LEDs have a lot of light in the same wavelengths where chlorophyll absorption is highest (the peaks occur at the same wavelengths). This shows that these LED lights provide specifically those colors of light that plants need the most. By comparison, HPS bulbs give off a lot of light in the green and yellow ranges. The chlorophyll absorption at these wavelengths is very low, meaning plants can? T use this color of light.This is why good LED fixtures are so much more efficient than HPS: you? Re not paying for the electricity to produce a bunch of lights your plants can? When compared to cheaper brands, the Advanced Platinum Series lights give you more output in the red and blue ranges, plus they have infrared and ultra-violet diodes.
In the graph above, the ultraviolet range is the small purple peak on the far left of the graph and the infrared range is the small red peak at the far right. These lights all feature separate veg and bloom modes that have slightly different spectra. In vegging mode, the red light output is dialed back, since plants don? T need as much red light during this stage.As a result, the unit uses even less power and you save. Platinum LED do not provide PAR charts, but not many manufacturers do. Instead, they provide single PAR numbers for each light at various distances from the top of the canopy. The problem is: an individual PAR value tells you how powerful the light is dead center.
It tells you nothing about the intensity around the outside of the coverage area. Platinum LED claim to give you the highest PAR output per watt, but if all of that PAR is concentrated in the middle and the values a foot or two off center are very low, then the light would be useless for anyone growing more than one plant. I find single PAR values misleading and I have to say, I?
M a bit disappointed in Platinum LED here. I know most LED manufacturers use figures that are slightly misleading, but there are also a few who don? T and I wish Platinum (and others) would follow their lead.Now the bizarre thing is this: the Advanced Platinum Series lights actually give you a pretty good light distribution throughout the coverage area. S not too far off the top brands, so I don? T get why they are using these misleading values. S something you would expect from manufacturers whose lights are sub par, but these are actually quality lights. I hope Platinum publish some PAR footprint charts for their lights soon.
The table below shows the PAR value (dead center only, unfortunately) and the coverage areas during vegging and flowering for each light at 18 inches from the top of the canopy. 4.5' x 3.5. 4.5' x 3.8. The reason there are separate coverage areas for vegging and blooming is that plants need less light during vegging.
As a result, you can move the light further from the canopy, which increases the coverage area (while decreasing light intensity). During flowering, plants need more light, so you have to move the fixture closer. This decreases the coverage, focusing more light on a smaller area. A common complaint about most LED lights is poor canopy penetration. Most LED diodes simply don?
T give you the same penetration as a powerful HPS bulb. This was actually my biggest worry in switching to LED. S not an issue here, though. Platinum LED lights get create a powerful light that penetrates as deeply as the top LED brands and also an HPS bulb (this is in part because the fixture can hang much closer to the canopy).
Overall, the Advanced Platinum series of lights are. Equal in light output and coverage area to most of their more expensive competitors. And they outdo any similarly priced lights.
Top-bin LEDs from quality US manufacturers like Bridgelux and CREE. These high quality diodes give you maximum output and reliability, while consuming less power. Each diode is also fully zener protected, to help guard against unwanted line surges. Rated for 100,000 hours. This is longer than almost all competitors and gives you 8-10 years of use without a bulb change.Each diode is outfitted with a 90 degree lens that focuses all the light downward onto the canopy. None of the light you pay for goes off in a different direction and is wasted. All of the lights use only 3 watt chips. These offer the best compromise between intensity and heat. 5 watt chips are more powerful and will penetrate more deeply into the canopy, but they also give off far more heat. 1 watt diodes give off very little heat, but they don? T achieve sufficient penetration to flower plants. Most top brands use 3 watt chips, while some have started using 5 watt chips. Personally I prefer 3 watt chips, at least for now. In the future when the more powerful chips become more efficient, I think we will see excellent lights using 5 watt and even 10 watt chips.
For now, the extra power is not worth the additional heat, since the fixtures need to be outfitted with heavy and expensive heat sinks and fans to take care of it. One huge advantage of using 3 watt chips is that they do not emit much heat. T provide numbers for the heat output (few manufacturers do), but all the P Series lights emit about the same amount of heat as their competition, which is, of course, far less heat than an equivalent HID bulb. What this means for you is that you won?
T need to run air conditioning units to deal with the heat from your lighting. S enough to just keep air flowing through your grow room. You just need to hang them (hangers included), plug them in and turn them on. There are two power switches: one for veg and one for bloom. Simply flip the veg switch for vegging and both switches for bloom.
I run my lights off 240 volts and Platinum LED lights automatically detect all international voltages. S no need to flip any switches; simply plug the appropriate power cord into the fixture (all international power cords are available) and turn on the power switch(es).
