    i always wonder if we could actually use an E27 spotlight bulb, with some lamp holder, and clip onto our tank to support the lighting.

    this is what i can think of and found...

    2 spotlight with clamp, 1 at each end of the tank.
    e27 spotlight readings are:
    Color temperature :
    -Warm White( 2700-3300K)
    -Cool white ( 5700- 6300K)


    Lumens
    -3W /300-300 lm
    -5W /430-460 lm
    -7W/:600-660 lm

    I'm suggesting this in terms of efficiency and cost.

    A good set of led lights probably will cost you more than $100 or more.
    whileas T5 is good but too hot for long hours..

    each e27 light bulb is somewhere $5 SGD for one, 5w.
    2 units will be around $10

    the lamp holder, neck is adjustable to 360 degree.
    around $10 x 2.

    the total cost is $30 and only uses 10W.
    the spread angle is huge, as e27 also come with lens for wider spread.

    what do you think? feasible or i'm too gullible

    I SUPPORT you! If you plan to try that is haha. I think it is worth a try, was thinking of the same thing some time back since led e27 bulbs are too cheap to pass.

    Re: e27 as light for planted

    It will work but you need to find the right balance.
    I will go with light temp 6500k if there is any.The 5700-6300k
    will work to but 6500k work even better.There are a few videos
    on you tube showing aquarist using DIY led spotlight for aquarium
    so it is do able... i myself uses t5 led tube 6500k,they save me a
    lot of money...

    OK, this is my finding.

    12w, with 1200lm, 60degree angle spread. 6500k, price is less than $10 usd.

    Where do you get your t5 led tube? I have been searching for it.
    To make sure we are talking the same thing, you reuse the casing like aquazonic, just replace the tube with led tube. No need additional driver etc

    I got it from hongkong ,you probably can get it at sim lim Tower.
    Yup, my first attemp i reuse aquazonic casing but i dont like it.
    I find that it is too compact and i cant get the light distribution
    the way that i want it so i end up DIY my own light holder.

    Here is the photo of my aquazonic 2 years ago.

    I tried searching for this T5 led tube before but no luck, it comes as a complete set with driver etc.
    Oversea, have them but It's not cheap.

    Hence I thought of this idea..actually I don't mind to use t5 if not for the heat.. it actually melt my dsm plants

    Re: e27 as light for planted

    Just to highlight some factors that contribute to the effectiveness of E27 LED bulbs... i've used them to replace all my home and office lighting for quite a while, so quite familiar with their application. At one point, i've also used a simple IKEA E27 desk lamp with E27 LED bulb shining over a small desktop nano tank for a period of time too.

    The 360° beam angle ones are usually those that have their LEDs arranged on all their sides (the ones that resemble a corn cob style design), so their light is divided and spread out in all directions, that is great for a ceiling lamp to light up a whole room (note that the lumens specs indicate the overall brightness we see but not necessarily what actually gets into the aquarium)... but on the other hand, for aquarium applications, you would want as much of the lights to be focused directly downwards into the aquarium (rather than have to re-reflect light downwards and hence lose overall intensity), so its more efficient to use E27 LED bulbs that have all of their LEDs pointing in one direction (the spot light style ones). The path of all the light is directional, so you can ensure there is no wasted light going sideways. To increase the light coverage, just adjust the angle or increase the height of the lights.

    The Dymax Astro is basically a E27 lamp holder that is designed for conventional E27 bulbs, so if you use E27 LED bulbs in it, the horizontal placement of the bulb results in only one side of LEDs shining downwards into the tank, while the rest of the sides shine in all other directions and lose overall intensity when they have to be reflected back down.

    Instead of that, you can just look at getting the simple E27 lamp holders with clips from electronic shops (there is a shop at Sim Lim Sq called Unicell which has a whole display shelf of clip-on E27 bulb holders with flexible necks, they also sell E27 LED bulbs too), even IKEA also sells a good selection of lamp holders too. These E27 lamp holders utilize a vertical placement of the bulb and you can match it with E27 LED bulbs which have a directional light focus for better efficiency.

    Btw, the cheap no-brand E27 LED bulbs that are typically ordered from online china sites (or value hardware shops) are not exactly super reliable compared to the more expensive name brand ones (there is a reason why they are so much cheaper), i've used a few of the cheapo ones before and some of them failed after just a short period of usage (though i also have some of the cheap ones that are still working well for more than a year), so i guess the quality control naturally tends to get abit dodgy at the cheaper end of the price scale... so if you are buying the cheap ones, its best to order more for spares just in case.

    To add, here are some good examples of DIY light systems using simple lamp holders:



    This one has some nice style...

    thank you, UA for sharing.

    i actually went to ikea to hunt for this lamp holder but none could seem to be trustworthy or suitable..
    its either wall mount (i can't drill any holes on wall)
    or the neck is too short... i don't want a scenario whereby i used halfway, the lamp dropped into the water..



    Unicell, interesting. i guess i will pay them a visit on this sat then.
    i guess the horizontal light focus that you are referring, looks like this.
    Attachment 45051

    someone in oversea actually uses 2 x dymax astro on his tank:
    Attachment 45052

    i feel, in order to support the e27 or this idea, the lamp holder is important and must be reliable.
    The goose neck if you call it, must be strong and don't give way easily.
    anyway, dymax astro is cheap, less than $15 i suppose??
    so far, no accident nor incidents on this product..

    actually a few members privately message me, stating their interest in this project.
    as for myself, i'm still procrastinating..

    Yah this project has the potential to save us planted tank enthusiasts alot of money on lighting. 👍

    So what are you actually looking for?
    the holder or the led?

    ermm, nothing actually..

    i found the holder and also the range of e27 light bulb to consider..

    just waiting to see if anyone else got better idea/solution.
    dont want to impulse buy and resulting to waste.

    also don't know if really can works

    It will work,since you have a lot of tanks at home,
    try it on a small tank. What i did, i bought the ikea lagra lamp
    and convert it into led light,i dont have pics to show you but here is
    an example from the net.

    Yeah, the IKEA ones are mainly for placement on desks or clamping onto the sides of desks/shelves... none made for clipping on aquarium tank glass.

    Btw, this was the IKEA lamp holder i used, its the "old-school" clamp-to-desk style design with spring-loaded arms. I removed the hood cover since there is no need to use hood reflectors with directional E27 LED bulbs (makes it look alot less bulky too).

    Yeah, those are the best ones for E27 lamp holders which have a horizontal mounting position (like the Dymax Astro).

    You're right... the E27 lamp holder definitely has to be super sturdy, especially if its to be clamped on the aquarium tank glass. The Dymax Astro is cheap and a very suitable holder to use, since its already designed for that purpose. You also get a free conventional E27 bulb included too (if i remember based on the unit i used a few years ago), can re-use for home lights.

    thank you, UA for the encouragement and kind words..

    this is a difficult topic.

    i tried the ikea lamp that you shared, the neck design or the holder is kinda weak, it actually drop when we testing it.. hence didn't consider.

    out of the sudden, i can't find any more Dymax Astro..
    I tried C328.. seaview too, don't have it..

    anyone knows where can i get dymax astro?
    I intend to get a unit, measure the maximum length that i could fit a E27 into the slot.

    I even consider aquazonic clamping light but they are using PL tube instead. limited space that i could play with, Dymax astro still seems better.

    a Question:
    6500k is the advisable color temperature for plants.
    then how much lumens should we consider to hit a depth of 1ft?

    i have spotlight of 12W, with lumens of 1050-1200
    while 6w, with half lumen of 12w.
    both are at 6500k.

    if all failed, i might consider doing the spot light again.
    My only concern for now is the blindspots of the tank, due to the limitation of the neck of the lamp holder.

    I was at sim lim tower today, realized i didn't read the message well..
    Unicell is at sim lim square instead..
