Opinion/info on these bulbs

[TheEquineFencer]

They are relamping from T8 to these LEDs at work. Until these, I'd never seen a LED replacement with L-N on the same end. How common/hard is it to get these locally around the USA?

What might the cost of these be if bought locally or online?

Is there an advantage to using them versus ones that are rewired for L-N at each end?

Keystone is a legit manufacturer in the lighting industry. The problem with these tubes is that they're single end powered, which is older technology that hardly anyone uses anymore. If you are converting from T8 to these, then you'll likely have to change the sockets as well, which adds material cost and labor cost, quite unnecessarily.
Some manufacturers have stopped making single end powered tubes already. I'd be concerned about being able to find them in the future.
Currently, these tubes run about $7 or $8 to lighting retrofitters from electrical supply houses. Most any supply house can get Keystone products.
Hope that helps.

2x4 fixtures mainly, they are retroing everything T12-T8 -T5 to LEDs.

I'm still at work right now with the lighting crew. I've not had a chance to surf the internet for prices. I hate doing that on cell phone.
