What is the brightness level of these levels... Lumens or Candles. What is the optimal current draw/LED? Technical specifications.

You are asking questions of other buyers as if we were the manufacture. I don't have any technical specifications but I would say that they aren't very bright at all, I wanted to use them in a turn signal application --- No way you could see these in bright sunlight, I didn't return them, but I bought two other solutions, one is a 5 meter strip, waterproof and much brighter and then I ordered two other strips that I hope are much brighter. As far as current draw I have a 30 AMP supply with a digital Amp Meter on it that can show down to 0.10 AMPS. These didn't even register on the Amp Meter. There isn't such thing as an Optimal Current Draw for LEDs. It totally depends on the type of led and how many are in the strip --- They draw what they draw at the rated voltage, A bright LED may draw 10X the current a dim LED draws. I would say that for a strip this length to be bright at all, it would have to use LED chips that when in an approximately 12" strip it should draw about 0.25 Amps at 12Volts.

To the best of my knowledge, the brightness levels of this wonderful pocket light are 260 and 13 Lumens (high and low). I've had mine a couple years now....always on my belt!

I don't know the exact lumens but the 600 led drivers over the 300 is amazing you won't be disappointed , I used them for under cabinet lighting in kitchen

Hello,we use the Brightest 3528 SMD LEDs for these,Actual working luminous flux about 420~460Lumens,thanks!

Sorry, I don't know the lumens, it uses 2) 3volt lithium cells. i only use it for lighting my car locks or my pack to find stuff. the light is flood and not spot so not a huge distance. I use it frequently and have not had to change out the batteries yet, so for my purpose it is worth the cost.

Hello Light waves, With no spec for lumens or CRI on Amazon, I'm almost as much in the dark (NPI) as you. However, I've had one of these running in a decorative spotlight for a few months, so I can make some comments. The color of the light is much better than a CFL, but not as nice as incandescent or the legendary Philips L-Prize bulb. Comparing it with various Philips and Cree LED bulbs that I'm currently using, I'd say the CRI is probably around 80, certainly no better than that. That's just an eyeball estimate though, YMMV. Brightness is roughly equivalent to a 25-30w incandescent bulb. If you use it in a reflector spotlight (I'm using it in an old boat searchlight - the reason I needed a bulb with a BA15D base) it makes an odd but interesting pattern on the wall because of all those individual LEDs spread over a large area. It doesn't dim very well, even with a PWM dimmer specifically for LED lights. However, after my initial experiments, and given it's modest light output, I never attempt to dim it anymore. You probably already know this, but just in case, be aware that this bulb has a BA15D (both bayonet pins at the same height) base. This means you can put it in the socket backwards and it will not work (I've done this a few times, it didn't destroy the bulb). Many bayonet base LED bulbs on the market use the BAY15D base (pins at different heights), preventing it from being inserted backwards. I have found the descriptions - even on Amazon - to be wrong about the base type occasionally, so always look at the pictures carefully to be sure the base type is what you need.

It is hard to tell, but I have not noticed any dimming. The last line in the Technical Details section seems to say that it dims to 1500 lumens near the end of its rated lifetime, but it has a long lifetime, and that sounds like something all LEDs would do.

I've read somewhere they output 1200 Lumens with power at 22 W. More or less it compares with a 75W incandescent according to some charts. This doesn't take efficiency into account. I'd say a bit more than 75 after having had those for about a year. HTH.

Their claims seem a bit off, it's more like 1200 to 1500 lumens. Elsewhere datasheets show 67 lumens per watt Epistar LEDs and current measurements show 23W INPUT, so you do the math subtracting for inefficiencies since output must be lower than input power. It's still a good lumen:price ratio but the actual lumen range is helpful to know for comparative purposes.

The number of LEDs is unimportant. The output as measured in lumens is what is important. That information is not provided for this product. LEDs are not all the same, even those that output light in the same narrow spectrum; design and thermal specs matter, input voltage and current matter. 9 LEDs of one design could easily outperform more LEDs of another. If you want answers, demand to know the output as measured by an industry standard like lumens or candlepower.BTW, I attempted to ask that question specifically here, and that question hasn't appeared. Draw your own conclusions why that might be. The number of LEDs is unimportant. The output as measured in lumens is what is important. That information is not provided for this product.

They are LED of course, so they pull little current. I am assuming much less than one amp. If you are trying to relate them to an incadecent headlight/foglight bulb... 20-25 watts is a guess. They are the brightness that you would expect compared to factory LED strip lights. However, I am frustrated with my second set of these and would not suggest them due to the quality of solderjoints and assembly.

Hi. I own 2 sets of these. They are small LED light. Low energy but nice light output. Hope this answers your questionShane

According to the box it is 'SUPER BRIGHT 275 LUMENS ', ALSO 'LUMENS' are brighter than 'candlepower'. Hope this helps.
