$12 bu whatever, it's high CRI and facing the right way so just curious what it will do

I use E27 LED too (3000k & 6500k).

They work just fine for bloom.

I buy mine off eBay for $0.80/30w LED, or 100 30w-er's for $80. They sell them in quantities of 20 for around ~$35 (prices change often).

The new LED options run considerably cooler and make heat management much easier. With my 19 bulbs in a 2'x4' tent, I use a 400cfm fan + filter exhaust combo in order to keep temps within range.

You wouldn't believe it, at least I didn't until I saw the lights in person, but the new QB LEDs are WAY brighter than the E27 LED, or at least mine. That aside, the E27 LED will grow just fine, it's what I've used personally for the past few years, they are just not as efficient, but also much cheaper up front, a true 300w light for $30 is tough to beat. :cool:

EDIT: maybe try to remove globe cover? I wonder how much light that cover is absorbing?

One week of photosynthesis and there is actually some growth going on :shock:

there was a thread on Icmag that went into testing different home bulbs

but maybe gone now

Those bulbs pull probably less than 5watts. So your "300watt light" statement isn't very accurate.

They are ~28w real.

I've broken them down and each bulb is 3 strings of 12, 6.1v measured per 2835. The driver puts out .39A, I'll let you do the math....

After they heat up they settle in at about 27.5w.

@ChiefRunningPhist has used and electrically tested them too...

15min later..

They settle a little lower to 27ish+ but didn't want to wait (and I think you get the point), and if a fan is used instead of laying flat on the ground lol they maintain closer to 28.5+

Their issue is the heat. Its 30w dissipated via 60mm×62mm MCPCB. No air flow inside case, and driver definitely doesn't cool anything down haha! They can get up to 180°f on PCB surface! I thought they'd be pretty handy @ $0.80/ to use only the PCB part in a custom build and drive with a meanwell and use proper heatsinks, but I haven't put it together yet. It won't be very competitive efficacy wise, but a fun little project.

If using these you'll want a 24/7 exhaust, they are cheap and they work, that is their value.
