屋外LED投光器とは？
屋外LED投光器は、スタジアム、駐車場、建物のファサード、倉庫、庭園、建設現場など、広い屋外エリアを照らすために設計された、高輝度でワイドビームの照明器具です。
従来のハロゲンランプやメタルハライドランプとは異なり、屋外LED投光器は発光ダイオード（LED）を使用して、熱と電力損失を最小限に抑え、明るくエネルギー効率の高い照明を生成します。
仕組み
LEDチップは、HIDランプのようにフィラメントの燃焼やガス放電を起こさずに、電気エネルギーを直接光に変換します。
定電流ドライバは電源を安定させ、LEDを保護します。
ヒートシンク（通常はダイキャストアルミニウム製）は熱を放出し、LEDの寿命を維持します。
強化ガラスまたはポリカーボネートレンズは、ビーム制御と衝撃保護を提供します。
この構造により、防水屋外LED投光器は、 雨、雪、沿岸部の湿気、または埃っぽい建設現場でも確実に動作します。

How to Choose the Best Outdoor LED Flood Lights?
Choosing the best outdoor LED flood lights is not just about wattage or price. You need the right brightness, beam angle, waterproof rating, heat dissipation, and certification—especially for stadiums, factories, or high-mast installations. Below is a practical buyer’s guide.
Buyer’s Dos – What You Should Do
✔ How many watts or lumens do I actually need?
Always calculate based on lumens, not just watts.
Basic formula:
Required Lumens = Area (㎡) × Lux Standard
Example: a 500㎡ tennis court (300 lux) → 500 × 300 = 150,000 lumens → around 6–8 pcs of 200W LED flood lights.
Application | Lux Level | Recommended Power |
Home yard / driveway | 50–100 lux | 20W–50W |
Parking lot | 50–100 lux | 100W–200W |
Football field (training) | 200–300 lux | 400W–600W |
Professional stadium | 500–1500 lux | 800W–1200W |
✔ What beam angle is best for stadiums or facades?
Beam angle affects light distribution and uniformity.
Use Case | Recommended Beam Angle |
Football / tennis fields | 15°–45° narrow beam for long-distance throw |
Basketball courts / parks | 60°–90° medium beam |
Building facades, billboards | 90°–120° wide beam |
Wrong beam angle = dark spots or light pollution to neighbours.
✔ IP65, IP66 or IP67—what’s enough?
IP65: Resistant to rain and dust. Suitable for most outdoor led flood lights.
IP66: Stronger water jet protection. Good for stadiums, ports or heavy rain areas.
IP67: Can survive brief water immersion. Used for coastal or extremely wet environments.
✔ CRI and color temperature—does it affect broadcasting or safety?
CRI ≥ 70 is enough for industrial use; CRI ≥ 80 recommended for sports and TV broadcasting.
Color temperature 5000K–6000K delivers bright, daylight-like visibility, ideal for sports and security.
Lower CCT like 3000K is better for landscape or residential comfort lighting.
✔ Heat dissipation & material—why aluminum housing matters
Choose die-cast aluminum housing + pure copper heat pipes to lower LED junction temperature.
Prevents light decay and extends lifespan to 50,000–100,000 hours.
Avoid plastic shells that cause overheating and color fading.
✔ Certification & warranty—UL, CE, DLC, Ceramiclite 5–10 year warranty
Always check if the led flood light outdoor is certified:
UL / ETL (USA), CE / RoHS (Europe), DLC Premium (for energy rebates).
Ceramiclite sports and industrial lights provide 5–10 year warranties, ensuring long-term reliability and maintenance support.

Buyer’s Don’ts – Mistakes to Avoid
❌ Don’t only look at wattage. 400W LED ≠ 400W halogen. Look at lumens and efficacy (lm/W) instead.
❌ Don’t ignore beam angle & pole height. A 15° beam on a 6m pole will waste light; match beam angle to mounting distance.
❌ Don’t buy the cheapest floodlight without a good driver and heat sink. Poor-quality drivers are the main cause of LED failure.
❌ Don’t skip certification. Non-certified lights may cause flicker, fire risks, or fail inspections.
