Off the shelf retail store screw-in LED and CFL bulb comparisons

[brown_thumb]

that pic looks like P or Cal one could even lockout the other, i think

when you wire bulbs, plus and min dont matter, just think of 1 for power in 1 for power out

Huh? Polarity doesn't matter to a diode?

Costco has 10 packs of 14w LEDs for $30. Here's a picture of said 10 pack and a how to pop the lenses off step by step.

If you don't mind spending a couple extra bucks (this ones $13 at home depot) go get cheap bathroom vanity lighting fixtures, wire a plug to the end and you're ready to grow. No real wiring knowledge necessary.

Thank you! I have a very small veg/flower room. Will 2 bulbs work for veg, 4 for flower? Anything that can mount as flush as possible? Can these led bulbs be mounted from the side?

 

[sillyhead123]

For example...need space up top. Of course power supply mounting is bad like this, and I only have access to one plug for my 10 plug powerstrip also.

In such small places unsoldering the plate with LEDs from the bulb base and mounting on a flat aluminium for cooling is the right stuff

easy, safe? any tutorials on how to?

GreenMember, Naw I dont think its light burn. When I was vegging with just LEDs and no MH , My LED bulbs where 2inches away almost all the time. The only time I would even get A little burn would be when I didnt check on the girls for 2 days and the tops where pressing against the LEDs. I was using the 15watt and 13/14watt LED Bulbs..

It looks more like a nutrient problem, p related, or an o.d. of some kind...

If it's from heat the buds would be crispy too, from too much light you get bleaching. Those leaves look more twanged to me.

 

[sillyhead123]

Can anyone confirm these bulbs can be ran on the side?

Going to snag this for veg and flower room, and rig it to plug. Simple easy mounting

if you connact led bulb to a wire and plug into a socket, you can plug it in any way you want, upside down, downside up, flipped, switched the driver takes the power however it comes

^^^ Thanks... I didn't know that.

Can I mount 3 in veg, 3 in flower through a 3 outlet extension cord? This enough for .8sq feet veg/flower?

i do 1.2 sq ft with 3 bulbs, still cfl's at the moment, but good results
will be switching to the led's soon
and from what i see here, 3 should do you well
but those more experienced will be better sources

 

[Bishop916]

Are there any safety concerns with using led bulbs with the globes removed?

 

[chronosync]

Yea the little chips get hot AF and could def set something on fire given a chance, bare "bulb" led will burn holes in your eyes. Especially with micro grows, I'm like IN that little tent and I come out seeing stars

 

[ice-cream]

no electricial issues as the voltage is very low.
but like cronosync has posted, temps might be an issue if anything touch the mounting plate

 

[chronosync]

i tried up to 60w per sqf but theres no benefit, its better to stay 30-50

wow thats a lot. now that i know how bright led are (per watt, so bright man)

did you notice any negative effects at 60w/sqf?
how careful do you need to be bringing them into that?

So I took off a couple of "globes" today and hooked the bulbs up to power. I don't know if it's my imagination, but after being on for about 5 minutes, the housing seemed much hotter than what they had with the globes on!

I would have thought they would end up running cooler as the heat could escape more easily. Has anyone else noticed this or is it somehow my imagination?

Thanks blynx,
This thread is tres chic! Just read through the whole thing and I'm very tempted to buy a box of Philips 13w 2700k and give it a try!Also thanks to Terp and the rest of the guys dialling this in!
BTW it stuck with me in my mind that the "no name" bulbs are usually quoted with less lumens per watt than let's say the Philips bulbs which are quoted at 1521 lumens in the 13w 2700k version...They're slightly more expensive, but I think I'd go with a name brand...

No name bulbs putting out less light at same wattage, is that something you guys have noticed and / or experienced in your runs ?

cheers
