How we picked
This guide covers the whole pool for the under $300 window: 3 LED grow lights whose live prices are under $300 at reading time. Each listing is compared on the details stated in its own title: light type, watts, coverage area, LED chip maker, dimmable and timer. The ordering rule ranks by stated watts first, highest first; listings that state no watts come after those that do. Then it ranks by the number of stated details among light type, coverage area, LED chip maker, dimmable and timer, most first. Ties are broken by the order in the pool file. Prices are printed live with the time of reading and are never used to rank. These LED grow light reviews compare stated details and live prices side by side.
How to choose
What 'under $300' means here
This guide covers LED grow lights that are under $300, as the keyword says. The page prints each live price with the time it was read, and prices change over time. Nothing in this guide ranks by price; the ordering is by stated details only.
Board, bar, strip, bulb or clip-on
The three picks here are two bars and one quantum board. Bars and boards hang above plants, as a general fact; strips line shelves, bulbs fit a lamp socket you already have, and clip-on lights hold onto a pot or shelf. Which type suits your space is a layout question, not a plant-result claim.
What the watts on a title mean
The watts figure in each listing is the draw of 1 light, as the title states it. A title that names an 'equivalent' wattage is not stating the draw. In this list, only one pick states its watts: 280W. The other two do not state watts, and this guide writes 'not stated by the seller' for them. More watts means the light draws more power, as general advice; it does not by itself say how much light the unit gives.
Tent and area sizes named in a title
Titles here name growing areas as width x depth in feet. A 2x4 ft title is 8 square feet; a 4x4 ft title is 16 square feet. This guide reads the largest area the title names. It never claims the light covers that area evenly or suits a plant stage; hanging height and placement come from the maker's manual.
Dimmers, timers and apps as listed
All three picks state a dimming control in their titles. One of them, the Spider Farmer G5000, names app control. None of the three titles names a timer. If you want a timer, you can add one separately, following the maker's instructions for the light and the timer.
What to read in the maker's manual
Numbers like PPFD, hanging height and hours of light are not in these listing titles. For each model, read the maker's manual and the product page on the maker's site for those figures. Follow the maker's manual and local electrical rules for installation.
Questions
Where can I read PPFD, hanging height and hours of light for these lights?
The maker's manual and the manufacturer's product page for each model are where you read PPFD, hanging height and 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. No light-number figures are repeated here.
Do all three lights have a timer?
No. None of the three listing titles names a timer. All three state a dimming control, and one also names app control. If you want an automatic on and off cycle, look for a model whose title names a timer, or add a separate timer and follow the maker's instructions.
Why is the AC Infinity IONFRAME EVO3 listed first?
Because of the ordering rule: lights that state their watts come before lights that do not. The IONFRAME EVO3 title states 280W, a 2x4 ft area, Samsung chips and a dimmer. The other two titles state no watts, so they follow it in the list.
What does a 4x4 ft area in a title mean?
The title names a width and depth in feet. 2x4 ft is 8 square feet and 4x4 ft is 16 square feet. The guide reads the largest width x depth the title names. It does not mean the light covers the whole area evenly; hanging height and placement come from the maker's manual.
Do the prices on this page stay the same?
No. Each live price is printed with the time it was read from the store, and store prices change. Check the buy button for the current price at the moment you buy. This guide never ranks lights by price.
