great value led bulbs

i was wondering if these bulbs are the correct ligh spectrum for plants. they have them in 2700 and 5000 light apperance. i was thinkng about switching a couple of cfl for these led. 100 watts uses 15 watts and puts out 1650 lumens. i got two and they are bright.

No one's too into bulbs anymore but you'll probably not get a lot of endorsement of those bulbs around here. Without knowing who makes the LEDs it's tough to say how effective they will be. The CREE bulbs at Home Depot are probably cheaper than those bulbs if you can get some of those Green discounts some states have. The CREEs are probably better quality than the one's you get at WalMart.

But to answer your original question yes the spectrums are right enough.

Those look pretty similar to the Phillips LED bulbs I bought at Home Depot, same shape and about the same lumen/watt (one of the few screw in bulbs I've seen that have > 100 lumen watt). The price looks the same as HD too. I wonder if they are re-branded Phillips bulbs?

I've been using the 5000k for veg for about two years. 4 of them keeps my 4x4 rotating.

These are the type of bulbs you want nowadays. So much less wasted light than with 360° bulbs. Bonus if you can remove the COBs and upgrade them occasionally.

Do you have a link for those @FranJan ? I'm interested in supplemental lighting for an indoor lettuce/spice garden, and if those are decent priced I might pick up a couple and use the Phillips bulbs to light my garage.

Offhand I don't know what brand is better than another. Alibaba has these bulbs as kits so one can choose which COB they want to use. But Amazon sells these:

I tried to add up how many of these a person would have to buy to match a single cxa3070 cree cob,, and I ran out of fingers and I shook my head ,, to many bong hits, lol,, nobody is going to beat ya up for sticking with your screw in bulbs, they are easy,, but more than one of us will try to bump you towards much better ,, much much better ways to make light around here

As Fran pointed out lots of light wasted to the sides. I wouldn't use them to flower but they work for veg. For flower I'd definitely use something more intense.

I bought 3 20w cool white wall wash units on fleabay. $21.00 for all shipped. They work well for my 6 plant veg. I have some veros and a couple cc drivers but I'm to lazy.

i revert to lazy on a daily basis,, lol ,, good one

Chuck those Great Value into a home fixture....and NOT a CLOSED FIXTURE EITHER!

You can search my post history on here...I posted a review on some of these way back in Late '13 ....They get about 15-20 Degrees C hotter than the equivalent Cree/Phillips bulb of similar wattage....probably lack any kind of real heat sink....

They are pretty shitty for growing to put it mildly.

Try the ones at Home Depot....I saw a sale the other day for less than $5 per bulb...Crees....Mine still work fine after 2.5 years of use.

Indeed Tim, it was the wild wild west a bit, all these bulbs hitting the market, and peoples first chance at getting any kind of decent diode even though it is was in light bulb form...

This was basically pre-Vero's, and that wasn't all that long ago

thanks for all the input. i always like help and love this site.

a bit more power in one of these!

or you could go with a cxb3570 cree led and have 13,000 lumens

It's depressing looking at the lm/w efficiency of most of the screw in bulbs. While they are an improvement over incandescent and CFLs, when compared CXBs or Veros, they are awful. The best screw in bulbs I've seen are the Phillips or Great Value bulbs at about 103 lm/w, most are < 100 lm/w. I was somewhat excited when seeing the bulb PB posted, since it's putting out 2200 lm, but it takes 30w to do it so the lm/w is only 73. I've gotten used to seeing lm/w values of 160 - 200 in this forum, so I guess I'm expecting the same from bulbs, which probably won't happen for a few years. It'd be great to be able screw bulbs into a couple of the clamp-on lamps to use for side lighting or supplemental lighting - not saying you can't do this now since the bulbs will grow plants just fine, but they are not a very efficient solution as Tim has been noting.

Just stumbled on this video and company and thought of you guys . I love the design for a COB bulb grower. Especially with some of those new Samsung COBs which really up the LPW and have a much smaller LES.
