Comparing RGB 150 to RGB 300 at night


Santas Helper

Recommended Posts

I purchased a roll of RGB150 and a roll of RGB300 to compare the brightness.

The 150 strip is on top the roof. The 300 strip is around the garage door.

Both are the IP65 M5 5050 16' strips. Both reacted the same to the LOR DC controller.

I was surprised to see that there was little difference (I expected more). The 300 was little brighter and fuller and looks more like a neon tube. And it was not blinding like some folks mention.

The farthest pic (green) was taken around 120' away. The closest (red) was around 20' away.

Both strips were purchased from ebay. The 300 strip cost $27 with free shipping and took about 4 days to get (shipped within the U.S.). The 150 strip cost about $17 with free shipping but took almost a month to get (shipped from China).

In person and from about 70' and further away, it would be hard for locals to tell which is which without knowing IMHO.

Edit: I temperarly "stapled" these to wood trim.

Hope this helps those inquiring the difference at night and side by side.

Tom, the 300/per looks good, like you said, almost a solid line.. the green pic, is that the 300 or 150 light? Who did you get the strip from the US from?

Appreciate the comparison pics. I've also heard about the 'blinding' result of the 300s, but, like you, I'm not seeing it. Now that you've seen the results first hand, is it worth the extra $10 to get the 300s and everything that goes along with it (power consumption, etc), or will you be sticking with the 150s?

TJ,

In all three pics, the top roof line is the 150 and around the garage is 300. The 300 looks just a little brighter than the 150 in person.

I got the RGB 300 (located in the U.S.) from Seller :

I think I'll pay the extra $10 for a little fuller look. But I'm also thinking about time. I plan to use these for Halloween (orange and purple) and want to line out the rest of the house. So a little more cost to get them next week is what I prefer as well.

You can really tell with the green. seems much brighter. Nice work.

Thanks Steve, Yes, the green stands out a little more. The white is just as bright but not blinding IMHO.

I'll get more pics hopefully tonight.

Tom are those strips in a silicone sleeve or in resin i have some ip68 and are in a silicone sleeve and filled with resin and it makes them look brighter ???

I guess I better ask before answering, what would be the difference in silcone or resin? I don't see anything like a sleeve.

These seem like a flexible rubbery formed over the components.

TJ,

Is that common knowledge coming from a pilot, a bad dream, a forum member? or all three? :lol:

These results may not be as clear cut as what the pictures show. the reason being that the strips were obtained from 2 different manufacturers.

Why could this be important you may ask. It all goes down to the construction of LEDs. The process of making LEDs is not a perfect process and LED lights will be manufactured with differnt intensities for different colours. To overcome this limitation the LEDs are 'Binned' into sepertate buckets of LEDs which have different intensities. This is done so if you puchase a strip or a bunch of LEDS that the light emitted is not inconsistant across the strip or LEDS used. So different manufacturers will purchase different LEDS based on the binning process, the less light emitted the cheaper the LED is usually. So to compare 2 different strips from 2 different manufacturers is not taking into account the possible differences in the LEDs used.

But after all that, the best thing to do is to buy lights at the same time from the same vendor for elements like roof lines gutters, matrices and any element where the LEDS will be used together to make up 1 element as this helps ensure the LEDs with in that element will have consistancy.

The 300 LED/M strip shouldnt be more blinding than the 150 LED/M strip as the brightness is dependant of the 5050 LEDs ability so a 300 LED/m strip shouldnt be any harsher on the eyes to a 150 LED/m strip but the 300 LED/M will definetly stick out in a display that is mixed with traditional LEDs and throw out a lot more light. The 300 LED/m strip offers a more 'neon' effect as the LEDS are much closer together.

As far as the coatings on strip, the silicone tube is easier to work with, more fragile. The solid resin and silicone coating methods offer more strength and better light dispersing properties but are harder to work with.

And finally the strip that you purchased, is it the strip that just has the coating on the top and the tape on the bottom because if it is i have heard several reports of this type of strip failing prematurely due to water getting in from the underside and the top coating lifting from the strip. So something to just keep an eye out for if you have this type of coating as this is what is commomly sold on EBay. I would like to here how it fares for you if it is that type of strip so we can learn from your experience.

Hummmm, I'm going to have a beer and re-read that.

All I got was not blinding but more light. ;):P

Man, all this on a friday night....... :blink:

What i mean by that is that the 5050 LEDs based on the binning process will only emit a certain amount of photons in the light emitting process, So as far as the eye sees the individual LEDs it shouldnt be that much harsher because the points of light emmission will only allow so much light to be emitted. In the 300 LED/M strip there are just more points of light emission, but the the actual harshenss/intensity shouldnt be much more. Now if you had 1 or 3 watt LEDs then they would be much brighter points of light and harder on the eyes

from what I can see up close you can see the difference but at the end of the driveway (green picture) where the people will be they are very close in appearance.

The reason for this is due to the percentage of light being seen versus the your field of view, so the closer you are the brighter the lights will appear as the % of your field of view versus the % of light seen increases. So the closer you are the more difference your eyes will see between the 150 LED/M and the 300LED/M, but from the street the % is much lower so the brightness differences are much closer.

I can see what your talkin about with my comparison.

Thanks for the explanation.

Yes, these strips have the sticky backing.
