PlatinumLED Grow Light Review

With all of the different grow lights available on the market, it can be a bit overwhelming trying to decide which are the best for your indoor gardening needs. Since they can be fairly expensive, you don’t want to have to go through a lot of trial and error to find exactly what you’re looking for in a grow light. To help you navigate the world of grow lights, today we will be looking at the Advanced PlatinumLED Grow Light review.

There are many different models to choose from in this series: the P150, P300, P450, P600, P900, and P1200. Since they share a lot of the same features, the one that may be right for you mostly depends on how much power and coverage you need for your indoor garden.

Who is PlatinumLED?

PlatinumLED is an American-owned and operated family business that is based out of Kailua, Hawaii. On their website, they claim to have the highest-level PAR per watt of any of their competition in the world of LED grow lights. This is highly debatable, but let’s take a closer look at their product features and specifications.

PlatinumLED Grow Light Review: Product Specs

Since there are so many different models to choose from in the Advanced Platinum Series of grow lights, we will only review the specs of the Advanced Platinum Series P300 as an example, as it is arguably the most popular unit in this series. This should give you an idea of what to expect from the other models.

  • Dimensions: 19 x 8.5 x 3 inches
  • Weight: 12.8 pounds
  • LED Type: 3W LEDs from US manufacturers like Bridgelux and CREE
  • HID Replacement: 400W HPS Light
  • Power: 300W (100 pieces x 3W)
  • Spectrum: 12 band full light spectrum, including UV and IR
  • Coverage: maximum coverage of 4.5 x 3.8 feet, core coverage at 3 x 2 feet
  • Voltage: AC85V-260V
  • Lifespan: 100,000 hours

Now, let’s take a closer look at what goes into these grow lights:

PAR Output and Coverage

Unfortunately, PlatinumLED doesn’t provide PAR charts to give you a better idea of how their lights should perform, but this is fairly common among grow light manufacturers. Instead, they provide just a single PAR number at the center of the veg and bloom coverage areas at various heights for each model. See the table below for the values at 18 inches from the top of the canopy.

ModelBloom Coverage (feet)Vegetative Coverage (feet)PAR (µmol/m2/s)
Advanced PlatinumLED P1503 x 1.54.5 x 3.5545
Advanced PlatinumLED P3003 x 24.5 x 3.81050
Advanced PlatinumLED P4503 x 2.54.5 x 41385
Advanced PlatinumLED P6005 x 26 x 3.751535
Advanced PlatinumLED P9005 x 36 x 41615
Advanced PlatinumLED P12005 x 46 x 5.51827

There are different values for the vegetative and bloom coverage because plants don’t need as much light when they are in the vegetative stage. Therefore, the light can be moved further back from the cover, giving you a large coverage area.

You do need to keep an eye on your plants though, as once they start the blooming stage you will need extra light intensity, so the light needs to be moved closer to the plants, decreasing the coverage area.

If you are familiar with the average PAR values for these types of LED grow lights, you can see that the light intensity is pretty great with the Advanced PlatinumLED series. These lights are just about equivalent to the more expensive top brands in terms of light output, making them superior to most other LED grow lights at this price point.

PlatinumLED Grow Light Review: LEDs

Platinumled grow light review: LEDs

The Advanced PlatinumLED grow lights use top-bin LED bulbs from Bridgelux and CREE, which are known to be quality manufacturers in the US. These kinds of quality diodes help ensure that you are getting an effective and reliable product while still maximizing output.

Each diode also has a 90-degree secondary focusing lens that helps collect and evenly distribute the light throughout the entire coverage area. They are also Zener protected, meaning they can help protect against line surges.

Though there are stronger diodes on the market today, PlatinumLED uses just 3W LEDs. The company claims that its 3W diodes can outperform any 5W, 6W, 10W, or even COB LEDs when it comes to consumed wattage due to an improved efficiency curve.

While it is debatable whether or not this is true, you may be wondering why you would choose to go with a grow light that uses a 3W diode instead of a more powerful option. In short, the stronger the diode, the more heat it gives off. To ensure effective heat dissipation, this means that the grow light needs to be equipped with fans and heavy heat sinks, which can be expensive. Speaking of which…

PlatinumLED Grow Light Review: Keeping It Cool

Platinum LED grow light review: Cooling System

Though it doesn’t give off a lot of heat to begin with—thanks to its 3W diodes—the Advanced Platinum Series of LED grow lights come outfitted with aluminum cooling heatsinks and fans for effective heat dissipation. Keeping your grow light cool also contributes to extending its lifespan, which is an impressive 100,000 hours.

PlatinumLED Grow Light Review: Full Light Spectrum

As you can see in the first graph, PlatinumLED’s 12-band spectrum has been designed to match the absorption rate of various kinds of chlorophyll. The second graph shows how their competitors stack up when it comes to chlorophyll absorption rates, and there is a very clear difference. They simply do not provide the same peaks in the red and blue ranges of color that are important for plant growth.

You can also see that the PlatinumLED brand provides small peaks in the UV and IR ranges unlike some competitors, which are denoted by the small purple peak at the far left and the small red peak at the far right respectively.

With the veg and bloom switches on the Advanced PlatinumLED grow lights, you can also customize the lighting to match the stage of plant growth and even save power. For example, with the Advanced Platinum Series P300 grow light, turning the veg switch only draws 93W of power. Then, when your plants are in the flowering stage, turn the bloom switch on to draw the full 180W of power.

This kind of system allows you to not only give your plants just what they need when they need it, but it also allows you to save power and money on electric bills.

Customer Service

When you are spending a fair amount of money on a grow light, it’s nice to know how the company treats its customers well. Right off the bat, PlatinumLED offers a 5-year warranty and 90-day money-back guarantee on their grow lights, which is far better than some of their competitors.

As for people’s experiences with PlatinumLED’s customer service, the reviews seem to be a bit mixed. Some people say that their customer service is amazing, and they have had their questions answered and any replacements sent promptly, while others seem to have a hard time getting ahold of their team. More of the reviews seem to be on the “amazing” side, though, so that’s a good sign!


The Advanced PlatinumLED grow light series doesn’t seem to have any major disadvantages. There are a few minor things like it doesn’t appear to have daisy chain features and it’s not waterproof, which means it may not be ideal for large gardens or those with outdoor grow tents or greenhouses.

The other minor disadvantage is that the coverage area is slightly smaller than that of top brands. Arguably, the price of the Advanced PlatinumLED grow lights make up for the lack of coverage.

PlatinumLED Grow Light Review: Final Thoughts

At this price point and with this kind of performance quality, you won’t likely be disappointed if you decide to invest in an Advanced PlatinumLED grow light. While they may not be the cheapest units around, you will still be getting the performance that compares with top brands at a fraction of the price.

So, if you are looking for a grow light that gives you a high PAR value, decent coverage area, separate veg and bloom switches, low heat emission, and a full spectrum of light using top-quality American-made LEDs, then you should be satisfied with just about any of the offerings in the Advanced PlatinumLED Grow Light Series.

On the other hand, if you are someone who needs a waterproof grow light with a daisy chain function, then this may not be the unit for you.

Overall, our final verdict is this: it’s unlikely that you are to find a better grow light for this price.
