Need some serious lighting in my garage for a temporary spray booth. Picked up a "3000 Lumen" R bulb. Claimed to be equivalent to a 350.
Well, 300 L is actually about what a 200W incandescent puts out. Claims 30W. Pulled 42. Just looking at the output, I would believe about 2000L max.
Watched some video's on flashlights. Incredible output claims. Most produced about 1.5% when tested! Yea, a 100,000 Lumen light would burn your hand in seconds and start a fire at 2 feet and to produce that much output, would need 500A. Not going to happen from a Li-Ion cell. I have a 16,000 L flashlight and it gets too hot to touch in a couple of minutes. An expensive one and I believe the specs. A lot of LEDs and 5 Li-on cells.
Now in my shop I have some fairly expensive (4 years ago ) 4 foot 50W LED fixtures. They claim 4000L. I can believe close maybe. Not getting more as the buzz too loud. I have several of the infamous HF Bauer 5000L shop lights and for the dirt cheap price, darn good. Claim 60W which the math works out to be within reason.
Now the actual question. Looking for specs I can believe. Are there brands that don't lie?
Has anyone used those daisy petal kind of lights? Surface area for cooling does not look to be anywhere near enough for their power draw. Some current/Lumen specs seem close to reasonable though. 150W or so.
