I have a grow light for starting seeds with a high output 4' T5 6500K 54W light bulb (not sure of lumens off hand). I have an extra 4' shop light with slots for two bulbs, so I thought I'd rig it up for some extra lights on my seedlings (never a bad idea to have more light, right?)
I bought two daylight 6500K 4' T12 bulbs (at least that is what the cardboard sleeve said): (e.g.
http://www.amazon.com/Sylvania-24477.../dp/B000BO5A1Y)
- Color/Finish: Daylight
- Color Temperature: 6,500K
- Average Lifetime: 20000 hours
- Lumens (light output): 2180
- CRI: 88
But when I took them out of the cardboard sleeve, one of them was actually a 3400K 4' T12 aquarium/terraium/grow bulb (e.g.
http://www.amazon.com/Sylvania-24671.../dp/B000M2TX22)
- Color Temperature: 3,400K
- Average Lifetime: 20000 hours
- Lumens (light output): 1700
- CRI: 89
At first I wasn't pleased, but then I thought the mix of 6500K light and 3400K light might not be a bad thing. Any thoughts on these two bulbs for seedlings? Compared to just two 6500K bulbs?
