e27 as light for planted

[Mystikboy]

Lumens is a measurement unit to calculate brightness as perceived by humans.
For plants, the more relevant measurement would be PAR value.

The problem with aftermarket light bulbs is that they don't reveal the par..
Only lumens, can't blame them.. only aleck like me, exploring on this...


So what's the acceptable par that plants actually needs?

Bro, try them?

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.

Yeah, you need to turn the fastening screw knobs tightly on that IKEA lamp holder so that its secure... or else it'll very easily drop over.

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.

Looks like you'll have to check the smaller LFS and see which have stock, its quite a common light set at most places, probably most shops shift their stocking to LED lights nowadays so CFL Lights become less popular.

I managed to find my old set in storage, did some measurements... the length of the cover is around 13cm, though you actually don't need to cover when using directional E27 LED bulbs anyways, therefore it can just be removed. So you actually don't have any limitation on the length of the E27 LED bulb.

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.

6500K would be fine... i guess you'll just have to test them and monitor the plant growth to see which intensity are suitable for the setup.

Interestingly, i checked the original CFL bulb that came packaged with the Dymax Astro and its labelled as 7500K.

haha, ok, pardon me again.. never good at such stuff, butter fingers..

i realise a flaw about such clamp light, the goose neck is kinda weak..
i wonder over time, will it actually give weak..

now i got my astro light, going to buy my directional E27
but christmas came early for me.. was sharing with my wife yesterday on the agony topic of lighting and she offer to get me a up aqua u series as a Xmas gift.

haha, now.. is to buy or don't buy..

ok, i just order 4 led light bulb, since i'm the originator..
had to spearhead this project till the end.

If your wife is still buying the aqua u for you, why not try e27 on one tank and commercial aquarium LED light on the other tank and compare the results?

By the way, the optimal lighting for plants is actually between 6500k to 10000k, although 6500-7500 is preferred.

The other 1.5ft tank is using evo18..
Tested and proven..

I just wanna be nice, help her to save money. Go ahead with the E27 directional and if it really fails..
I will use the E27 for the house and get her to pay $123 for the u series

Keke,i am cunning..

Afterall, this hobby is about collecting stuff..
From bottles, to filters, to lighting set.
So what's next..

Rocks, driftwood.........

Rocks, driftwood.........

already have 14 pcs of rocks where i spend $40 on them, where i also becoming a laughing stock for my wife..
spending money on rocks

driftwood, i got 2.. wanna sell, also difficult..

this hobby is expensive.. with zero ROI.
the amount and time you pump in, you won't even get anything close like 50% of the initial.

maybe only for the top notch products, you still could savage your initial capital.

I'm still a newbie and know nuts about light requirement for aquarium.

But this is what I did for my tank light as originally lighting was for a small tank.

Modified the existing aquarium light fixture with what I had at home (just shifted home) so I didn't spend more $.
Using a E27 5W cool white led bulb, holder and wrap up with aluminium foil (like lamp shade) as reflectors.
Picture after installation and brightness of the tank.

Upon switching on the light for first time, the fishes were more playful, swimming in the last time dark areas.
Still monitoring if the brightness is enough for the plants and fishes.
I'm using a timer to set for 8hrs as recommended by my friend.

*thumbs up*
creative.

I didn't pursue further with my initial ideas.. lazy and wanted an easier way out.

good to see that it works for you
