Reddit reviews AmazonBasics 100 Watt Equivalent, Daylight, Non-Dimmable, 15,000 Hour Lifetime, A21 LED Light Bulb | 6-Pack

Other folks are giving very technical answers. They are correct, but you'll have an easier time just looking for bulbs labeled as "daylight" bulbs. This is the typical marketing name for 5000k color temperature bulbs, so you won't need to go reading all the fine print to find what you're looking for.

Hope this helps! :)

I would not LED strip, its clumsy, lots of parts, and so on

Suggestions:

1. I would repair the wire connection and use a candelabra LED bulb [I think candelabra is the right socket shape?], which will put far less strain on the weak splices than the old light did because LED uses far less amps. Thats the easy option, use the brightest bulb you can find
   
2. Adapt to a normal socket size [you lose space in the glass cover because of the adaption] Use 100w LED bulb
   
3. LED light engine retrofit
   
4. Replace the socket with a Type A normal socket size, which opens a vast number of LED light bulbs to you, like this very bright LED bulb [you have to check how long these special bulbs are, minus screw base, plus the socket depth etc]

Don't buy that. As a rule, you should have 32 true/actual watts per square foot. The one you linked is rated only 4-6 W.

In Southern California, I believe you'll be able to put them outside soon. Therefore, I don't think you need to buy something as power intensive as the one linked by /u/GuyoFromOhio, especially for two plants only. Something between 20-30 W should be enough, even taking into account some waste due to it being white. Either grab this if you have two spare/old lamps, (on the plus side, you get another 4 for your house) or a higher rated single bulb (LED or CFL), although it will be more expensive.

The lightbulbs I chose

not particularly sure on exact wattage seedlings require but know it’s not much-

The Hue bulbs aren't known for high output, no. The wattage to output equivalents are only estimated (as compared to incandescent bulbs) but the Hue bulbs are generally ~9w or so which his pretty low. The light color is also going to have an effect on perceived output and I've found the Hue bulbs to be far more shaded than most generic LEDs.

Most of the mega-low power consumption bulbs are going to be "60w equivalent". If you look for 100w equivalent you'll generally get a bit more light. These are rated at 11w and 1400Lm compared to Phillips' 9w 800lm. You should see a difference in output and for only a few hours a week, the difference in consumption will literally be pennies.

The Pentium G4600 has a TDP of 51watts, which if running 24/7 would cost $58/yr @ 13cent/kWhr

The $135 build comes in a little under powered (4910 vs 5450) but would be ~$170 cheaper (135 vs 302). The TDP on the xeon is 95watts, for the sake of math if the server actually was running 24/7 at max TDP it would cost $108/yr worst case. So it would take more than 3.5 years to break even.

This $297 build matches his budget (297 vs 302) but has a huge performance gain (8010 vs 5450) as well as more ram (12GB vs 8GB). The TDP of this xeon is also 95watts. Absolute worst case scenario this build will cost $50/yr more ($4/mo).

Whats hard to quantify is how often will the cpu hit the max TDP? What would a real world kWhr/yr number be? This was also assuming 24/7 operation, I can tell you that my server is not maxed out 24/7. If this is shortened to 12/7 operation then your talking about the difference of $2/mo in electricity for 3k more passmark.

Replacing two 100watt bulbs with a 14watt LED (assuming 3hr/day use) saves ~$26/yr which should more than make up for the xeon @ 12/7 use.

In the future if you want some pretty nice lighting, pick up some 100w daylight bulbs and put them in some cheap lamps (I picked up 3 used lamps from Goodwill for $3 and just removed the shades). Put one directly to the left of you, one to the right, and one above and slightly to the front. Amazon has a pack of 100w daylight bulbs for about $20 that are super bright. It makes for a pretty damn nice looking setup for around $25, and it's not really distinguishable from a much more expensive setup.

Thank you for such a comprehensive reply. Normally I would treat this sort of thing as a keep trying/keep failing/try again sort of thing, but since it was just one packet of seeds and one pot, I didn't exactly have that luxury! But you have inspired me, I would love to learn this stuff so tomorrow I'm gonna pick up a few more seed packets and things to grow them in! Anyway, back to these sprouts...

The good news-- it's not a mug, but a real pot, with holes in the bottom!

The bad news, I haven't dumped water that comes out the bottom, so it has probably reabsorbed it. I'm guessing the lack of growth is from that + not enough light

However you make it sound like I do have a chance at saving them if the pot has holes. Sounds like they need to get outside ASAP. I'm assuming I should still harden them first?

The window they're (right) next to has a screen.. should I mix in some time with that open in addition to a regular hardening schedule to give them some extra oxygen & exposure?

Also unfortunately I have no idea what soil I used, as it came in a gift baggie from my friend. However he grows a lot of houseplants & vegetables at home so I'm hoping that would mean it's something with at least some nutrients! I'll ask him tomorrow too

As for location, I'm in LA. Unfortunately a cold spell hit just today, and forecast shows the next week with highs of low 60s, and nighttimes getting down to low 40s, so it sounds like it's too cold to move them outside permanently for now

If it is too cold to take them outside, how do you feel about using Daylight LED bulbs? At the suggestion of someone in my xpost to HotPeppers, I ordered these: https://www.amazon.com/AmazonBasics-Equivalent-Daylight-Non-Dimmable-6-Pack/dp/B01MSMKBG3/?th=1 , but I may instead just pick up something like this at the store tomorrow: https://www.homedepot.com/p/Philips-100W-Equivalent-Daylight-5000K-T2-Twister-CFL-Light-Bulb-414078/203349671?cm_mmc=Shopping%7CTHD%7Cgoogle%7C&mid=siCqjagOR%7Cdc_mtid_89037lm25188_pcrid_227841299674_pkw__pmt__product_203349671_slid_

Any thoughts on using one vs. the other vs. neither?

Thank you again for the help!!
