How to distinguish my CFLs? (WILL REP)

[omar924]

I got a bunch of free CFLs but how do i know if there 2700k or 6500k? or something in between? if i post pictures of them can you guys help me out?

 

[Bluntcuts]

yea post pics. might not be able to tell exactly what kelvin temp they are but you will get a good idea

2700k is like an amber glow....6500k is a bright white light.... you can test each one you will notice a difference if they are different.

 

[RC7]

and ill add just in case you didn't know- 2700k is for flowering and 6500k is for veg.

Many of them have it in small type on the ballast portion of the bulb. 2700k are really yellowish and super easy to tell apart. 6500k and 5500k look fairly similar.

 

[omar924]

alllllllllllllll

 

[omar924]

theres one that says 27k on it...so im assuming its 2700k. but the one that says that is really really white. are you guys sure its not the other way around? 2700k is real white bright and 6500k is orangish.

i have a smaller cfl in one of my rooms for "actual" light and is the least output of all of mine. its only a 60 watt equiv (orange-ish color) whereas my cfl's for growing are 100 watt equiv.

No man I use a variety of 27k and 65k in my cab, and you can really tell between the daylight and amber ones. I have noticed that the 27k's are usually marked while the 65k aren't?? lol but I know for sure that 27k for flowering are really yellow just me 2 cents brah.

man its just that...today i went to lowes and 90% of the cfls were 2700k. yet like 90% of the cfls at my house and my friends house are bright bright white...so i put two and two together....and figured that bright bright white must be be 2700k since thats mostly what they sell at lowes and almost all the bulbs ive seen are bright white. :/ if that makes any damn sense lol

wear a pair of sunglasses when you look at them, its really easy to tell blue from red, blue 6500k, red 2700k, use a sharpie write it on the base.....


judging from that pic, top left is a 13w 2700k, top right 13w 6500k, the other 2 are, 23 or 26w 6500k

one on very bottom is a 2700k right? its the most orange out of all of them

 

[unohu69]

oh, lol. i didnt even see that one there, stoner moment. yeah, looks it to me, maybe another 13w 2700k..

Top left is 2700k, bottom near tool is 2700k, other 3 in Y adapters are 6500K, this is obvious. Most commonly sold in stores is 2700k typically, though many stores such as walmart carry both. Use 6500k for veg, 2700k for flower. Or a combo of 3:1 or 4:1

Color Temperature (CT) - Color temperature, which is measured in Kelvin, indicates whether a lamp has a warm, midrange or cool color appearance. "Warm" light sources have a low color temperature (2000-3000K) and feature more light in the red/orange/yellow range. Light with a higher color temperature (>5000K) features more blue light and is referred to as "cool."
Higher k light looks whiter. Most of the small cfl's hit 5000k not 6500k

Yup, makes sense.... Use "daylight" style bulbs for veg (blueish/whiteish and also IMPOSSIBLE to find in 300 Watt equivalents btw - lemme know if u find somewhere that does carry these PLEASE! Home Depot does in soft white but not daylight, same brand and fuckin stupid!!) Any ways use "soft white" style bulbs for flowering, they're more of an orangish/yellow color.... Its pretty easy to determine bro, just takes looking at them long enough (which btw blinds you) ! Lol.... I like to mix em up though, as someone has already previously mentioned! Actually I grew my entire grow with NOTHING but soft whites, start to finish. Huge buds, may even do that shit again.... Haha! Mistakes make you a smarter grower and misery is motivation to be a BETTER grower! Keep those plants UNmiserable and you'll be to!

Happy growing!!

turn them on if they have a white or blue color they are for veg the yellow/orange are for flower. then after you figure out witcj is witch mark them with a sharpe.

 

[ca$hcropper]

Bulbs marked bright white, or soft white are in the 27k flower bulb, while daylight, or as I've seen ones in blue packages are 65k veg bulbs, hope this helps

Try Menards for those high wattage veg bulbs, in fact their entire electrical departments blow away Home Depot.
