Dimlux Ceramic-Discharge Metal Halide systems deliver a spectrum that's much closer to natural sunlight than typical high-intensity discharge (HID) systems. These state-of-the-art lamps generate a greater level of usable plant light (photosynthetically active radiation) and run with a blinding intensity that's immediately apparent to the naked eye. Dimlux has embraced this exciting new technology, creating an innovative range of systems that take all the positive attributes of the outstanding Expert Series and then supercharge them to step performance up to the next level!

Greater efficiency, you say? Yes! In terms of efficiency, Dimlux Expert Series Complete CDM Lights kick out more micromoles per watt (1.9 umol/Watt) than competing models. This essentially means that these units give you and your plants a greater amount of light output from the amount of energy invested.

  • A blinding intensity that's clearly visible with the naked eye
  • Highly efficient - puts out 1.9 micromole (µmol) per watt
  • Extremely high PAR levels

  • Adjustable output levels from 165W to 380W
  • The highest output (light) due to the overdrive boost UHF technology
  • The broadest dimming range of all digital ballasts
  • Soft-Start, Soft-Dim, Soft-Off function
  • Can be dimmed manually in 8 levels including the “off” position.
  • Fully Maxi Controller compatible - Can be variably dimmed and controlled
  • Extensive diagnostic indicator LEDs

  • Safety features for preventing short circuits, open contact, high temperatures, too low voltage, too high voltage

DimLux Expert Series 315W Benefits

  • Excels as both supplementary and standalone lighting
  • SBCS -Single Bounce reflector ensures minimal light loss
  • Brighter, cleaner light for maximum yield
  • Less Heat – reduced risk of heat damage to plants
  • Reduce cooling costs
  • No loss of vertical space – ideal for rooms with 8 ft ceilings
  • Available DimLux Maxi Controller (sold separately) for dimming to sunrise/sunset and when temperature, humidity, VPD and CO2 levels vary
  • Overall much greater output and yield than any other lighting system

Like the other major lighting systems on the market, Dimlux Expert Series Complete CDM units consist of the ballast, reflector, and lamp. However, closer inspection will reveal distinct differences – the most notable of which being that all three components have been integrated into one!

Dimlux Xtreme Ballast

The Dimlux Xtreme Ballast gives you 7 separate dim options – considerably more than any other competing product – so you can precisely alter light output to match the changing demands of ever-developing plants. Two boost settings are available for generating up to 15% extra lumens than is advertised on the lamp, and the Soft Start and Soft Off features to ensure you don’t get sudden surges of power when switching between “on” and “off” modes, protecting the product and upholding your safety. Utilizing superior electronic technology, the Xtreme Ballast operates very quietly and very efficiently, promising to save you money over time on your energy bills. It is reassuringly fireproof, employing a built-in processor to monitor the ballast-to-lamp connection and an LED display to inform you of the operating status, cutting the power in the event of a bad contact or short circuit. Output levels can be switched between the following settings: Soft-Off, 165W, 205W, 245W, 280W, 315W, 345W, 380W. With 7 settings, you have the flexibility to tailor your lighting to your plants demand based on environmental conditions in the grow area, ensuring that temperature stay well within range.

Alpha Optics 98 Reflector

The Alpha Optics 98 Reflector has been made from mesmerizing 98% reflective Miro Silver aluminum. Crafted in a unique and effective manner, it only lets light waves hit the mirror-like surface of the interior on one occasion before projecting them downwards to cover over your plants. The light is also steered clear of any unnecessary and unwanted interactions with the lamp, minimizing overall wastage. These two aspects conform to the Single Bounce Clear Sight principle (SBCS). Both sides of the reflector can be adjusted to manipulate the distribution of light and there are optional add-on reflectors for stopping light from hitting walls instead of floor space. The open nature of the Alpha Optics 98 Reflector helps with the passive cooling of the lamp, improving its efficiency and overall lifespan. A 50mm port on the top of the unit actually allows you to extract the hot air away from around the lamp – a smart inclusion and standout feature.

Dimlux Ceramic-Discharge Metal Halide Lamp

Dimlux CDM fixtures utilize ceramic-discharge metal halide lamps to produce a light spectrum that's much broader than other forms of HID lighting (like standard metal halides and HPS). Its output is more comparable to the light produced by LEP (light emitting plasma) units. LEPs actually have a slightly broader spectrum than the CDM fixture, but they simply do not compare in terms of brightness. You can see with your own eyes, as soon as you turn this Dimlux unit on, that it’s every bit as bright as its equivalent wattage in HPS, giving you the best of both worlds – a unit that delivers an LEP-style spectrum combined with HPS-style intensity! A truly exceptional all-rounder that will add much to the quality and size of your harvest. The lamp is optimized for the bloom phase with enhanced reds, but, because it's full-spectrum, it will produce the goods in both veg and flower – expect to see increased growth rates, tighter internodes, an improvement in overall vigor and an increase in final weight. Because of its full-spectrum, it's also great for the vegetative stages, triggering rapid growth, speeding up turnover times and increasing the overall efficiency of your indoor garden. With a healthy level of white light (at roughly 3100K) internodes stay nice and tight, eliminating the issues with stretch that occur when using lighting with narrow, inadequate spectrums. Come harvest time, you'll be left wondering what you did without one!

DimLux Maxi Controller (Sold Separately)

To get the most from these units, we recommend using them in conjunction with the Dimlux Maxi Controller. You can then do away with your contractor/timer setup and control up to 160 fixtures from a single point, scheduling on and off times and regulating output levels according to room temperature or VPD (Vapor Pressure Deficit) levels, so that plant temperatures always stay within range. If you chose to link up your light system(s) to a Maxi Controller (recommended – and an astonishing 160 units can be accommodated!), this sensational device will manage them all at once taking into account indicated day/night periods and minimum and maximum heat tolerances, applying even closer control with continuously-variable dimming rather than standard incremental dimming. The Maxicontoller is a remarkably intelligent and fully responsive grow room device that will comfortably manage numerous Dimlux Expert Series Grow Lights (Double Ended and CDM models) in order to maintain your preferred temperature settings. Impressively, it also has the capacity to run a CO2 generator and a humidifier. By being able to constantly monitor key environmental factors (sensors sold separately), the Dimlux Maxi Controller can quickly identify potential issues and then take a suitable course of action – altering light output, CO2 levels or humidity until optimum conditions are restored. Highly recommended for closed loop rooms and large grow tents.

Solid Budget Monitor Arm With a Few Trade‑Offs
Size: 13"-34", Style: Single Arm
The WALI Single Monitor Mount performs about the same as my VIVO single monitor arm, which was a pleasant surprise given the lower price point. Setup was straightforward, and the gas spring adjustment works well once dialed in. It holds my monitor securely and offers the full range of motion I expected—tilt, swivel, rotation, and height adjustments all function smoothly. That said, the materials and overall build quality do feel a bit cheaper compared to higher‑end arms. It’s not flimsy, but you can tell where costs were saved. If you’re willing to spend roughly 60–70% more, you can definitely get a noticeably sturdier and more refined arm. Still, for a budget option, this one delivers exactly what it promises. Pros - Works just as well as the VIVO arm in terms of functionality - Easy to install with both clamp and grommet options - Gas spring provides good adjustability once set - Excellent value for an entry‑level monitor arm Cons - Materials feel cheaper than premium alternatives - Build quality isn’t as high as more expensive arms Overall As an introductory monitor arm, this is an excellent choice. It does everything the VIVO arm can, just with slightly lower‑end materials. If you’re on a budget or setting up a simple workstation, it’s a great fit. If you want something more robust for long‑term heavy use, spending a bit more will get you a significantly more refined Monitor arm.

Sturdy and easy to assemble
Size: 13"-34", Style: Single Arm, Size: 13"-34", Style: Single Arm
Really impressed with this monitor mount. The build quality feels solid and sturdy, especially for the price. It holds the monitor securely with no sagging or wobble, and the adjustability makes it super easy to get the perfect position. It’s been absolutely perfect for my sim racing setup being able to move the screen exactly where I want it made a huge difference in comfort and immersion. Definitely feels like a premium product without the premium price tag.

The installation process was straightforward and didn’t take much time at all—even if you’re not particularly handy, it’s easy to figure out. What really stands out is how flexible the arm is. It adjusts smoothly in multiple directions, making it simple to position my monitor exactly where I want it. Whether I’m working, watching something, or multitasking, the range of motion makes a noticeable difference in comfort and productivity. It’s also very sturdy once set up. My monitor feels secure, and I haven’t experienced any sagging or instability. As a second screen mount, it integrates perfectly with my desk setup and helps keep everything organized and clutter-free.

Solid Build, Easy Setup
Size: 17"-49", Style: Single Arm
I picked up two of these mounts — one for my 34" curved LG ultrawide and one for my 30" MSI ultrawide — and both have performed exactly as advertised. Build Quality & Value For the price, this thing is built surprisingly well. It feels solid, looks clean on the desk, and doesn't have that cheap, flimsy feel you'd expect at this price point. Genuinely impressed. Assembly & Installation Setup was straightforward. Everything you need comes in the box. The only tool you'll need to grab yourself is a ½" wrench — have that ready before you start and you'll be done in minutes. Mounting Options Two ways to mount it: clamp-on or through-hole (use an existing grommet hole or drill a new one). Both options feel secure once locked down. Sturdiness & Adjustability Once mounted, the arm holds firm. No drooping, no wobble. Repositioning the monitor is smooth and easy — tilt, swivel, height adjustments all work well even with the larger ultrawide panels. One Thing to Watch The tiny limiting screws ship loosely packed inside the arms. They're small and easy to lose if you're not paying attention when you open the box. Dump the contents carefully over a flat surface before digging in. Bottom Line If you're on the fence about a monitor mount, stop overthinking it and grab this one. It handles large ultrawides without breaking a sweat, installs fast, and won't break the bank. Highly recommended.

Initial thoughts
Size: 13"-34", Style: Single Arm
Getting everything set up took a bit of time and patience. The adjustment system wasn’t the most intuitive at first, and I ran into some confusion while trying to dial in the right positioning. However, after working with it for a while, I was able to get it pretty close to exactly how I wanted it. One thing to note is that making very fine adjustments can be a bit tricky. The mount is also slightly wobbly, and it’s fairly easy to bump the monitor out of position if you’re not careful. It’s not a dealbreaker, but it’s something to be aware of if you prefer a perfectly stable setup. That said, the overall construction feels solid and well-made, and once it’s in place, it does its job effectively. For the price and functionality, it’s a reliable option that gets the job done—even if it takes a little effort to get there.
