62 Watts Worth Of Light (A Link)

i was thinking of removing the TWO 15w tubes
and placing TWO strips against the reflector
re-wring the fixture

other members have done it with different LED's

when i look a replacement tubes made of leds and cost $30 each and less light
i walk away

regulation
well when i use the lights the most NIGHTIME
i'm strictly on battery power
unless I need the A/C the genset is not running in the evening
and then only in permissible hours

Mexicowanderer, point taken. So, should we be impressed with this "6000 lumen" LED light strip or not? :)

Compare the light given off by a good CFL, like a 26-watt GE daylight (equals a 100 watt bulb) to an incandescent 100 watt and I will be dipped if I can't see a LOT better with the CFL.

It don't add. The physics. 2+2 = 9,213,616

A hundred watts, right? Well how many watts, the percentage, is given off as infra red with an incandescent light bulb? You can't end up with forty percent of the energy expressed as heat and a hundred percent more added on expressed as photons.

Some bright individual has to work on lumens philosophy and translate the current gibberish into rendered light quantity. Of all the disciplines I have browsed this one is the most muddied, malleable and controversial. Someone casts out a number. It and the other hundred billion "lumen" claims are as valid as your everyday 3 dollar bill.

I buy a 600 lumen light and compare it to another 600 lumen light. I will kiss your... well anyway, they do not emit the same amount of light. Take your pick doesn't matter if they are 3,000 K or 6,000 K

I have seen 300 5-meter LED strips that do not give off as much light as my dinky 9 watt daylight CFL. But they are rated for more lumens, and more watts. I don't mean SPREAD OUT. I mean coiled up strips.

So as far as I am concerned learning or understanding what some of the PhD knotheads express as visible light is as meaningful as trying to learn Xhosa Click Tongue Language to aid in business meetings.

Damn! It's brighter! We'd better assign a higher number to it! This only is meaningful to the consumer if people are a) intelligent b) ethical

Crankiness of the day expended.

FWIW, using otrfun's figures here is the Lumens/watt.

Based on the stated power:-
3014 Min 90 Max 120
3528 Min 50 Max 133.3
5050 Min 66.7 Max 122.2
5630 Min 40 Max 80

Not a huge difference.

Edit: deleted the calculated Lumens/watt. My error. :S

Six thousand lumens is a lot of light . . . .

6000 lumens is the roughly the equivalent of four 100 watt 120v incandescent bulbs or 7-8 60 watt bulbs. The 6000 lumens put out by this strip is more directional and spread out over 16 feet. So, kinda hard to directly compare IMO.

Does not include the light fixture. Might work for indirect lighting. Otherwise how do I use this in my RV?

Six thousand lumens is a lot of light. Not long ago a 200 lumen flashlight was considered to be the 8th wonder of the world. This spells DEATH for shadows in my kitchen / dining room. SIX high wattage CFL lamps were previously needed. And guess what even GE lamps committed suicide frequently, and my IR thermometer detects 183F radiation. Just the thing I do not need in an ambient of ninety two degrees. Now, if I get only out wait the time it takes for a "more competitive" strip to appear...

Thats over $12 per foot and you need to use a regulated power supply.

Lumen (Brightness) - 6,000 per 16 feet, or 371 lumen per foot

These are pretty cool. This strip uses 3014 LED's (30ma, .1w, 9-12 lumens). They're brighter than 3528 LED's (20ma, .06w, 3-8 lumens), but not quite as bright as 5050 LED's (60ma, .18w, 12-22 lumens). Most of the LED's sold on eBay use the 3528 and 5050 LED's. The big kahuna of LED's for this type of lighting is the 5630 (150ma, .5w, 20-45 lumens).

IMO, the technology used here is more in the strip that holds the LED's, not so much the LED's themselves.
