When assessing LED floodlights, the price is primarily driven by Luminous Efficacy (lm/W) and the quality of internal components. High-end models offer >150 lm/W, while budget options hover around 90-100 lm/W. You must verify the LED Chip Brand (e.g., Lumileds, Osram, or Bridgelux) and the Driver Brand (e.g., MeanWell or Inventronics), as the driver is the most common point of failure. Additionally, ensure the Heat Sink is made of die-cast aluminum with sufficient surface area to prevent thermal decay, which directly impacts the product's lifespan and long-term ROI.
