Roleadro is a Chinese brand that’s fabricated in Shenzhen, China. They’ve been around for a long time and have established themselves as one of the most popular go-to choices in the introductory market.
The 45w panel by Roleadro is certainly a quality LED light at a cheap price. It comes with a switch that enables a lower power consumption mode. This 45W panel offers a great solution for people with a very tight budget.
The ballast gets mildly warm under continuous use 18/6hr. Mildly warm means 88-105f with an ambient temperature of 74f-88f. The backside of the panel is flat and made up of aluminum. It doesn’t get hot. Surface temp probe reads 82f on the metal backside after it had been on 18 hrs straight.
If you are in a hurry, then simply read below.
These panels are great for seedlings, microgreens, and houseplants, it is not suitable for any large blooming or fruit-bearing plants. However, you cannot yield marijuana under these at all.

Before diving into a deep review and results of experiments with this panel. You just need to know about.
Out of all tested LED multi-spectrum panels in the 60 watts (or below) category, these 45w panels delivered the 2nd best PPFD Photosynthetic Photon Flux Density and overall visible growth results in all plants when placed within extremely close proximity to the plants (micro greens)
The top light tested is the Taotronics 36w bulb which even beats out most of the 1200watt LED lights.
With the Quantum par meter, these panels put out 200-245μm (micromoles) at 3-5″. That’s impressive compared to the other cheap LED panels offered on Amazon which are putting out around 9-40μm and saying they are 4x the power.
The ideal effective range for these is very close 3″ to 8″ (max) for proper coverage. and subsequently limits the effective angles of usable light. You could place them higher, however, the PAR drops significantly after 1.5ft. Keep your expectations within scientific reasoning, don’t expect to bloom 16 Costco sized strawberries off this one single panel. However, you can grow two entire 20×10 trays of flowers on this easily. You can also grow a Single 20×10 of Microgreens (healthily) under this.
Since, you can’t grow marijuana under these lights
These panels are great for certain applications like seedlings and microgreens, it is not suitable for any large blooming or fruit applications. You cannot yield marijuana under these at all, you can, however, start seedlings. This is also perfect for sustaining Tissue Cultures and have been very reliable. This is also great Refugium Light for Aquarium Macro Algae.
Comparison with other lights
Roleadro vs Unifun

|Uses carabiner style hooks to mount||Uses threaded screws to mount|
|Has external power supply which is bulky and gets hot||Has internal power supply|
|No power toggle switch||Has a power toggle switch|

Roleadro vs Taotronics
The $26 Taotronics 36w LED grow light bulb puts out a whopping multispectrum 1500µmol at 1.5ft You would need a couple per plant for large fruits, vegetables or marijuana, but you cannot beat the cost factor and after running the lights for 24/7, you can easily fully grab the bulb/heatsink, unscrew it, and it won’t even be slightly warm.
