Quick Picks by Budget & Need
Mars Hydro TS-1000
Best budget light for 1-2 plants
Spider Farmer SF-2000
Best overall for 2-4 plants
HLG 300L RSpec
Best efficiency & quality
Key Specs to Understand
Efficiency (μmol/J)
Light output per watt. Higher = better. Premium LEDs: 2.7+ μmol/J. Budget: 2.0-2.5 μmol/J.
Coverage Area
Match light to tent size. Flowering needs more light than veg - buy for flower coverage.
Heat Output
LEDs run cooler than HPS. Look for passive cooling (no fans) for silent operation.
Running Cost
At $0.15/kWh (MN avg), a 200W LED costs ~$7-9/month running 18hrs/day.

LED Grow Light Buying Guide
1. Match Light to Tent Size
2x2 tent
100-150W
2x4 tent
200-250W
3x3 tent
250-300W
4x4 tent
400-500W
2. Samsung Diodes = Better Efficiency
Look for Samsung LM301B or LM301H diodes. These are the most efficient LEDs available and will save you money on electricity while producing better yields.
3. Get Dimmable
Dimmable lights let you reduce intensity for seedlings (30-50%) and ramp up for flowering (100%). Much better than fixed-output lights.
4. Don't Trust "Equivalent" Wattage
A "1000W LED" that draws 100W actual power is a 100W light. Always check actual power draw, not marketing wattage.
Frequently Asked Questions
How much does running an LED grow light cost?
At Minnesota's average electricity rate (~$0.15/kWh), a 200W light running 18 hours/day costs about $8/month. A 400W light costs ~$16/month.
How long do LED grow lights last?
Quality LEDs last 50,000+ hours - that's 10+ years of growing at 12 hours/day. Most come with 3-5 year warranties.
Do I need separate lights for veg and flower?
No. Modern full-spectrum LEDs work for both stages. Just adjust the height and dimming: higher/dimmed for veg, lower/full power for flower.
Is a $300 light really better than a $100 light?
Yes, significantly. Premium LEDs (Spider Farmer, HLG) are 15-30% more efficient, produce better yields, run cooler, and last longer. The extra cost pays for itself in electricity savings and better harvests.
