Cool, but I do not think these would give you what you are looking for.
Basically, led strip lighting, mounted in a T5 “bulb”.
I tried a pair of strips, with the same # of LED, would equal 2 of these units, and lighting was very poor.
Looked nice in a darkened room, but not so good during the day.
What the bulk of these LED units would need for our use, would be reflectors and light focusing lenses, for each LED.
For a LED, direct replacement lighting system you can count on spending quite a few bucks.
But, the good news is, as these find more uses and become more “main stream” the cost will go down.
New technology always costs the most at introduction and always goes down with increased use.
