Don’t Judge a Light by its Wattage!

Posted by Ventry Solutions, Inc. on

Lentry 240W, 336W, 750W and 1500W lights are many times brighter than 500W, 1000W and higher wattage lights.

Portable LED, Lentry Model 1STARX, lights the arena of the Therapeutic Riding Center of Huntington Beach (CA). This light emits 20,000 lumens using only 240 watts. Photo courtesy TRCHB.

Warning: Watts are no longer an accurate way to measure how bright a light is.

The wattage of Lentry® Portable Scene Lights will mislead most people because of their surprising efficiency compared to common frames of reference. All models, with both halogens and LEDs, are extremely efficient and brighter—many times brighter—than other comparable lights that draw many more times the power. The output:draw ratios on our LEDs are especially radical and will not make sense compared to what most people are used to seeing.

For example, the photos on this page show the Lentry V-Star LED which is 20,000 lumens but only draws 240 watts. (This LED is on all models with “STAR” in the model number.) This is many times brighter than most 500W or 1000W lights recommended for similar uses. These images are shown courtesy TRCHB.

No consistent measurement method exists among manufacturers. Additionally, the common units, lumens and candlepower, are not meaningful to most people. Therefore, consumers tend to erroneously use wattage to determine relative brightness of lights.

Comparing lights by their energy usage or power draw is especially misleading and unhelpful!

For example, a respected guide for illumination of nighttime flaggers suggests that for safety, flagger lighting should be at least 1,000 watts. 1,000 watts is how much energy a light USES, not how much light it EMITS.

A quick reference of Lentry Lights showing lumens vs. wattage is as follows:

 Lentry Light
Lumens (how much light is emitted) Wattage (how much energy is used)
Optup 19,000 750W
V-Star LED 20,000 240W
V-Spec LED 28,000 336W
2-Headed V-Spec LED 56,000 total 682W total
