Side by side

How we picked

This guide draws from a pool of 7 LED grow lights whose listing titles name a growing area of 4x4 ft or larger, meaning a coverage area of 16 sq ft and up. The group rule is that each title states a coverage of 4x4 ft or more, many sold for a 4x4 or 5x5 grow tent. The lights are compared on the details stated in each listing title: light type, watts, coverage area, LED chip maker, dimmable, and timer, plus live prices. The ordering rule ranks picks by stated watts (highest first; listings that state no watts come after those that do), then by the number of stated details among light type, coverage area, LED chip maker, dimmable, and timer (most first), then by the order in the pool file. No plant results or light intensity figures are used.

How to choose

What a 4x4 tent title means

A listing that names a 4x4 ft area states a coverage of 16 sq ft, and a 5x5 ft area is 25 sq ft. The title names the growing area the maker suggests, not a measured result. When a title says "Fits 4x4 Grow Tents" or "4x4", it is stating that coverage figure. This guide includes only lights whose titles name 4x4 ft or larger, so every pick is sold for a tent of that size or bigger.

Board, bar, strip, bulb or clip-on

Grow lights come in several forms, and the title usually names the first type. A bar light is a long, narrow fixture that often hangs above plants. A panel is a flat board. Strips and tubes line shelves, bulbs fit a lamp socket, and clip-on lights hold onto a pot or shelf. For a 4x4 tent, bars and panels are common, but the type is a matter of the listing, not a promise of plant results. Choose the form that fits how you plan to hang or place the light.

What the watts on a title mean (and what an equivalent figure is)

The watts key in this guide is the power draw of one light as the title states it. More watts means the light draws more power, which can matter for your electrical setup, but it is not a measure of light output or plant growth. Some titles give an "equivalent" wattage, such as a comparison to an old lamp type; that figure is not used here. If a title does not state a watt figure for one light, the guide says "not stated by the seller."

Tent and area sizes named in a title

The coverage area is the largest width by depth in feet that the title names, converted to square feet. A 4x4 ft area is 16 sq ft, and a 5x5 ft area is 25 sq ft. The guide never claims the light covers that area evenly or suits a particular plant stage. The title names the area the maker suggests, and your tent size should match that figure for the light to be a candidate.

Dimmers, timers and apps as listed

Some titles state that the light is dimmable, which means you can adjust the power output, often with a knob or an app. Others name a timer or an auto on and off cycle, such as 4/8/12H. These are stated details, not instructions on how long to run the light. The guide lists what the title names, and the maker's manual is where you read how to use the controls.

Samsung chips and other chip names

Some listings name the LED chip maker, such as Samsung LM301B or LM301H. This is a stated detail about the component, not a claim about performance. The guide never says one chip grows plants better. If a title does not name a chip maker, the guide says "not stated by the seller."

Questions

Where can I read PPFD, hanging height and hours of light for these lights?

The maker's manual and the product page for each model are where to read PPFD, hanging height, and recommended hours of light. This guide compares only the details stated in each listing title: light type, watts, coverage area, LED chip maker, dimmable, and timer. Light intensity figures and schedules are not in the catalogue, so the maker's documentation is the source for those numbers.

What does a 4x4 ft coverage figure mean?

A title that names a 4x4 ft area states a coverage of 16 sq ft, and a 5x5 ft area is 25 sq ft. This is the growing area the maker suggests in the title, not a measured result. The guide never claims the light covers that area evenly or suits a particular plant stage. Match the stated coverage to your tent size.

Why do some picks have no watt figure?

The watts key is read from the listing title, and some titles do not state a watt figure for one light. When that happens, the guide says "not stated by the seller" and never guesses. A missing watt figure does not mean the light has no power draw; it means the seller did not name it in the title.

Can I use a 5x5 light in a 4x4 tent?

A light whose title names a 5x5 ft area states a coverage of 25 sq ft, which is larger than a 4x4 ft area. The guide does not say whether that is suitable; it only reports the stated coverage. Check the maker's manual for the recommended hanging height and area, and follow the maker's guidance for your tent size.

What does dimmable mean on these listings?

When a title states the light is dimmable, it means you can adjust the power output, often with a knob, a switch, or an app. The guide lists this as a stated detail and never recommends a specific setting. The maker's manual explains how to use the dimming control and what range it offers.
