As part of our in-depth review series, I’d like to welcome you to my Advanced Platinum Series P450 review.

My first impression of The Platinum Series P450 is that it’s a small, self-contained grow light that packs a serious punch. The team at Platinum Series have developed their LED’s with the grower in mind, offering some serious technical features with a light intensity 3 times that of the nearest competitors. The P450 is a superb piece of equipment for small scale, ‘ghost’ grow projects.


Like all the Platinum Series, the P450 provides a powerful PAR light intensity. What makes the P450 stand out is you get a strong light, with UV rays all the way to Infrared, from just 150 individual 3W LEDs. With quiet cooling fans built into the fixture, the P450 gets your plants growing while producing little excess heat.

A 2 phase switcher comes built in as standard for the veg and bloom stages of crop production. They can be dual engaged to provide a 100% super intense light source for when your crops need the most light.

Furthermore, the 90-degree focus lenses let you feed light below the canopy and, to top it all off, you can plug it straight into the wall.

Coverage can sometimes be a tricky measurement in terms of visualizing how many plants you can grow. The truth is, plant sizes vary depending on the strain, the stages of growth and the conditions that you provide. I believe that a single plant needs a minimum of one square foot to cover all the stages of its growth. It’s also important to note that the mark I give for coverage is for the particular size and power of the product reviewed.

When your plants are in the veg stage, the P450 covers an impressive 4.5 by 4 foot area. That’s enough for 16 young plants but, once those plants start blooming though you’ll need to concentrate their light source. In the bloom stage, you can cover a respectable 3 by 2.5 foot.

What I really like about the P450 is the size. You can easily hang this in a 3 by 3 grow tent, or a tucked away cupboard.

For something so small, you get a great crop coverage, plus, the panel adapts to different phases of growth via the two phase switch; purple light in the veg stage and pink light in the bloom.

Strength and Efficiency

Regarding strength, the Platinum Series are the most powerful lights on the market right now. The P450 offers a 450W output from just 255W of electricity which is impressive. The only criticism I have of this series is that as the models get smaller, the efficiency tends to suffer.

Against a HID, or HPS, it’s a no-contest but, when comparing the P450 to other LED’s of similar size it’s not the most efficient. However, I do feel that the P450 more than makes up for that with its sheer strength of light.


The P450 is one of the more versatile grow lights around. The two phase growth switch not only adjusts the intensity of the light but also the spectrum, provided that you use it in the right size space.

I’ve knocked a few points off simply because you can only use this light for small-scale ops. But, no matter how small your operation, you’re guaranteed to make the most of it with the P450.


You can certainly find cheaper, but you’d be hard pressed to find an LED that’s better for this price. I think that the Platinum Series 450W is the perfect choice for beginners.

Additional Info

A 90 day returns policy. 100,000-hour lifespan with a 5-year guarantee. Additionally, it can be plugged into any type of socket in the world.

What I like

The light intensity, the switch phases, the cooling system. I pretty much love everything the Platinum Series P450 offers to first time growers.

What I don't like

Not much I can complain about, but if there would be something it would be that the efficiency could be a little better, as compared with other Platinum Series. Nonetheless, it will still surely offer a great yield and return on investment.

Bottom line?

If you’re just starting out, or you want to experiment with some smaller scale projects then the P450 is for you. The P450 has a number of features that make it difficult to get things wrong when you’re home growing. A great little piece of equipment.
