That would depend upon the parameters evaluated and compared to establish the quantitative meaning of the word <...better...>.

The forum has nothing to go on.

Why do you ask the question?

Buying outdoor lights?

Selling outdoor lights?

Installing outdoor lights?

Homework?

Just curious?

So as not to waste time, where have you looked so far?

Who have you asked so far?

I googled the title of your thread and got a very informative explanation.

I AN NOT going to post it here. You'll feel better about yourself if you find the answer all by yourself.

I noticed your avatar is a photo of Peter Terren, AKA Australia's 'Dr. Electric,' of Bunbury, WA, Australia, Peter happens to be an online friend of mine.

Now, had Peter asked this question, he would have provided a great deal more information, particularly what 'better' means in this context and not just a snarky definition posted here anonymously by you.

Good day.

Certainly Overly Bright is always better than Surely Mighty Dim.

As a circuit board designer and a board assembler, I would make no distinction between SMD and COB. My chip shooter doesn't care.

I realize that is not the question here.

Here less than 3 weeks. You catch on fast.

At least in this ping there's no overt reference to a web address in this poster's profile.

Call it déjà poo - that feeling you've stepped in this before?
