13w LED Bulbs

I'm not sure if this is the appropriate place to post this, but here goes. I have been looking at the 13w e27 bulbs that some of the sponsors of this board have recently started selling. I have a tank that I need to keep brightly lit, but the CFLs I am currently using get really hot. I am just curious if people have gotten good results from these bulbs before I pay $36 a piece for some. Anyone have any experiences with these? I have searched, but I can't find any specific comments on these bulbs.

I'm not sure but I just ordered the 11w jungle dawn bulb and I'm hoping they do great!

If you'd like to post some side-by-side comparison photos with these bulbs and some standard CFLs, that would be very helpful. :)

i have some from LYR and they weren't that expensive and they work great. I replaced two CFL's with one LED bulb on my smaller tanks and i've seen improved growth. Need to buy more.

I have a 13 watt jungle dawn that I am very happy with. It does put off considerably less heat than a 26w CFL and appears to be more powerful than the CFL I had before.

My only concern is the longetivity of the bulb. For the cost, I am expecting it to last quite some time. We will see. I will say that I plan to outfit the four tanks I am starting to construct with them.

My 2 cents.. :cool:

Hey!!!

I have the sponsor sold 13w jungle dawn LED bulb on my 12x12x18 exo, and I love it.

I also ordered 2 more 13w LED's, in 6000k, from China via ebay, for half the price. I'm still waiting for these in the mail, but I can post some comparison between the name brand and the cheap alternative if you guys can wait....Thanks!

Before Josh's Frogs started selling the 13w LEDs, I tried one out on an 8x8x12 nano tank. A 26w cfl bulb heated the viv up 8F over room temp - the 13w LED raised the temperature only 2F over room temperature, and was much brighter.

I order 4 13w LEd jungledawns from lightyour reptiles and soo far I am happy. It droped the bottom of the 18x18x24 for 4 degrees and the top by 2. Iv only had them about a week now so i dont know how they will do with my plants. So far I am super happy and will be buyinh more in a few months if I get good plant growth. Iv got 2 18 in zoomed fixture with one 13w jungle dawn and one 9 watt in each.

I have 3 of the original 13w 6500K led bulbs from LYR, I would have preferred the Jungle variety but they were not available when I got mine. I am extremely happy with the bulbs. They run a good bit cooler than CFL's and I have had great plant growth out of them. Plus using half the energy will more than pay for the difference in price in the long run.

First off I do sell the led lights from LYR. So I may be a little biased. However the results are well worth the upfront costs. If you have a tanks over 18" tall there are 24W spots available also. Plants, especially mosses grow exceptionally well. Heat difference comes in two regards.......first (tank), the difference in the heat given to the tanks.....second (room), the room is cooler overall resulting in the air conditioner having to run less. It has been several months since converting over from T5's, T8's, and CFL's to the LED's and my energy costs have decreased by over a third.........
Here are a few threads.......

In comparing the junge/mix led vs the 6500l only lights.............

I prefer the 6500K lights over my frog tanks. While I like the jungle/mix over my plant tanks. On my tall tanks I use a combo of lights........I am using the 6500K 9 ,11, or 13W lights with a mixed (jungle) 24W spot.
I just prefer seeing the frogs under the white light and know there is a benefit in photosynthesis for the mixed in my plant tanks. There is no need for the mixed diode lights for the frog tank, it is just a matter of preference.

I got the chinese knock off 13w 6500k bulbs and they are virtually the same. I can post pics later in the day

eBay: e27 13w led

I recommend spotlights. We're used to buying lights that shoot light everywhere, and we hope enough of it gets into the tank. With LEDs (which are directional) we don't have to think that way anymore.

I got some of the Chinese knockoffs myself, but I'm still waiting for them to come. I'm interested to see how they work for me. I'll post some before and after pictures when I get them.

Not the same. The ones sold by our sponsor have CREE diodes, as well as other top of the line parts. Would be interested to compare the output side by side as well as the actual wattage used. Just remember you get what you pay for.

I agree. CREE LEDs are a world apart from any other I have seen on the market right now and the spec sheets prove it.

The Chinese knock offs are likely using...knocked off LEDs...and I would question the SPECTRAL output of those lights more than anything (since "classic" LEDs are famous for not outputting full spectrum) as well as their lumen/watt efficiency...

I'd be shocked if you could even find a spec sheet on the chinese knockoffs, but at least a side-by-side comparison would be a good starting point.

Yep, it's true, you get what you pay for. Mine just came in today. They are very bright and run cool, but I'm not thrilled with the look of the light. It's very blue, like the 10,000k bulbs over my reef tanks. I'm going to give them a try for a few weeks and see how my plants like them, but I'm not holding out too much hope. So, interesting experiment? Yes. Great success? Not likely, but we'll see.
