T8 not much difference between 1600 and 3000 lumens

[robertearl]

I purchased the led replacment lights from Lowes. They were 1600 lumens. They just weren't quit bright enough so I orderd a few 3000 lumens from Amazon. These were a real disappointment. They were about the same brightness but cost three times as much. Am I missing something or was I just expecting too much?

Need links to products purchased to compare specs, claims and NRTL certifications (if any).

Here is the link to the ones from Lowes.

No way to confirm light output as neither appears to have DLC rating. LEDmyPlace does sell a DLC rated bulb (link). Suggest sticking with frosted cover. What's your mounting height?

They are on a 10 foot ceiling.

The ones I ordered were from LEDmyPlace. What does DLC rated mean???

A picture of the space would help. Is this a basic 4ft 2-lamp strip light? How big is the space and how many fixtures?

DLC ( https://www.designlights.org/ ) sets efficiency requirements on lighting. They cover the areas that Engergy Star doesn't. It's one way of confirming lumen output and power consumption claims.

LEDmyPlace has both DLC and non-DLC rated bulbs.

A DLC search of this WENT84DUA-20WB-D-50M LEDmyPlace 3000 Lumen claim shows it's actually 2600 lumens.

Here are pictures of my shop.

Nice space! I assume the lamps in the pictures are fluorescent? LED bulbs that are universal: ballast compatible & direct wire may have higher lumen output if direct wired. Still don't like the clear lens LED as they are harsh on the eyes. Narrower beam spread LED will make ceiling darker than fluorescent bulbs.

 

[robertearl]

Yes they are.

Did you find the clear lensed LED bulbs to be harsh?
They do make LED bulbs with wider beam spreads.

LED's are directional light.

There are other factors which affect the appearance of brightness such as CRI.

Looks like the same ones Im using - Utilitech With an 8' ceiling, the look better than the Phillips 6500k T8s.
