New LED lights reliability

<< < (12/24) > >>

timelessbeing:
I said lumen output, not power input.

A) they are tiny LED emitters so they will never product much light. These bulbs are usually used for decoration, not illumination.

B) There's virtually no thermal mass. It's extremely easy to overheat those tiny filaments. Power is intentionally kept low.

The 40W bulb you mention is ENORMOUS.

Kjelt:
The efficiency of modern filaments look to be up to par to smd leds if I google quickly.

It's also 240W equivalent, 100W equivalent ones are dime a dozen.

timelessbeing:
Wow ... a dime a dozen. That really is cheap.

And I'm sure the specs are 100% real too.

Marco:
100 lm/W was standard even for box store lamps four years ago. So yeah, those specs are real.
