LED as a light source

I've been searching for LED rope lights for a while and found them today at walmart. They're fairly cheap and i wanted to know what kind i need to buy. There are no "6000K" or any other reading of the same kind on any of the boxes. Are all LED's suitable? They have white/blue/red etc.

I don't think all LED's are suitable. Maybe some are. Probably best just getting a cool white compact fluorescent. The white ones might be suitable though. You really need to know the color temperature. Do they say anything about peak wavelength? I think you want 400 some odd nanometers. Do a search.
You *Might* be able to estimate it. If you can, plug them in and compare to a 'harsh' fluorescent light. If it looks 'colder' or about the same, it may be suitable. If it looks more like a standard incandescent (tungsten) or a 'warm' candle flame, it won't work.

I know they probably aren't recommended, but alas, once upon a time when I was very nooby I got myself some LED lights. One string was a NOMA Christmas lights string, the other some led lights in a tube. Both blue (yes i know, the misinformationous adventures of a newbie). I have used both in combination with natural room/day light and have not experienced pinning problems, ever. Just my experience, not a scientific conclusion at all.

I used white LED Christmas lights once. They worked but they were different than the ones you bought. Mine are patented bright white color lights. They don't emit that yellowish light like the ones you bought.

I don't want to through a 10w cool white CFL inside and get a lot of heat from it. At the walmart i found CFL's, tube FL's, and the LED rope lights. But the convenience of the LED's seems unbeatable. i believe they were somewhere from 400-500nm.

ive read that most production white led's (which are actually modified blue led's) put out blue light from around 450-470 which is just a little shy of the parameters listed on this site. i think in the clear rope, if they are in fact "white" led's, they will work fine. good luck.

BTW mushroom cultivator says 480nm. So ill check back with the lights tomorrow to see the wavelength.

Thank you. I'll check up on them tomorrow after i make up a few dozen quart jars and ill report back to this post.

I was thinking of grabbing a rubbermaid jumbo tote (It's almost 200quarts big) and thinking of using it for casings. For humidification i was thinking of using a small custom bubbler with perlite.

i like humidifiers. a cool mist ultra combo is great but that is a bigger operation. the thing about FC's you want to watch is consistency. set it up and get a thermometer and hygrometer in there run it for a week to make sure your getting consistent temps and RH's. no one likes a roller coaster of a FC. but also take into consideration that having stuff in there will change your readings.

yea, thats so true. my current grow is situated in 3 monotubs, so until my next batch of grains colonize, i have time to experiment.

I've used white LED rope lights (not from walmart) but they were probably still cheap Chinese junk. Do not get blue or any color, they wont be bright enough. I can certainly attest to white LED rope lights and highly recommend them. They are the most practical light you could use in this hobby. LED Rope lights give the most amount of light with least amount of power consumption and a very long string of bright light. This means you can effectively light up 10 mono tubs at the same time or a whole entire Martha unit.
FYI: white spectrum contains all colors of light. Your mushrooms will certainly get more than plenty of 420nm blue light from a full spectrum bulb to give them direction upward.
Remember: they are NOT plants, stop treating them as plants. They do not have high light demands like plants. If you want a better pinset, you need to practice your technique, period.

Thanks! I know they don't have light demands that a plant do, i was just wondering about the nanometer's necessary. I found in the mushroom cultivator that 420 for as little as a millisecond a day can induce a shit-load of premordia. Now that i know that, the rope lights that i saw were between 400-500nm for sure (from what i can remember) but when i go check them out tomorrow (1 minute walk to walmart), if they are in that range i will pick them up for my next super-stealth grow.

You have to have red, green and of course BLUE to make 'white' light....
Think about it: When you have a white light shining in a room and there is an object that is blue (the 400 nm), it is actually blue from the 'white' light that is being reflected by the material, which you perceive as blue.
which is what white LED are; i hope everybody understands this important concept.

I sure understand what your saying, that is why if you are in a darkroom with red light, you cannot perceive any colors besides red. Thanks for reminding me though!

i use this  its a rechargeable LED flashlight. i just turn it on and set it ontop of my tub it shines right through the opaque blue lid. i leave it there while im at work and charge it when i get home, probably not big enough for your purposes but white LED does work
