These lights came with the shelves I bought for starting seeds. I can’t find info for how strong these are – wondering if anyone here might be able to tell.
My seeds are germinating but my seedlings look rather tiny and slow-growing. Wondering if it’s anything to do with the lights. Maybe this isn’t enough info to give any advice, but if it is I’d love to hear your thoughts!

Tip: If you’re worried about lighting strength, then lower the lights closer to your seedlings.
This [eBay listing](https://www.ebay.com/itm/156639446834) matches the part number. If accurate, the “About this item” has all the specs you need.
You can try one of these apps to get an estimate. Not a true PAR meter, but good for a ballpark.
Photone
PPFD Meter
There are device apps that can measure the strength of your lighting.
