I'm currently using a 7W warm white LED light over my tumbling ball of Chaeto in my sump, but I want to see if I can get it growing any faster.

As Chlorophyll absorbs red light, and Carotenoids absorb blue light, these bulbs have LEDs in the right wavelength and proportions to grow green plants very quickly, in theory.

It seems odd shining a red light on the algae, but lots of people with ATS (algae turf scrubbers) are using red light, including the santa monica ATSs.

So I've ordered this now: http://www.ebay.co.uk/itm/-/110980105120

It'll be a direct swap for my current one, and will be more powerful (being 12W not 7W) and also with that light being concentrated exactly in the wavelengths needed, not wasting power outputting wavelengths not needed (in the white light).

It'll take a while to arrive, but when it does, i'll post an update to how better if at all noticeably it grows my ball of chaeto! :D

ATSs seem to grow faster, absorb more, but they require an electric pump as well as the light, and may also trickle, I've gone for the simplicity of a silent ball of chaeto tumbling in a chamber of my sump.

This is the light I've currently got: http://www.ebay.co.uk/itm/-/180737613418

It's the same one Tangman uses, and I got my cheato from him when I went to get the huge 12KG lump of live rock of him.

None of the LFS sell cheato by me. I may have to go further afield or have some posted.

I'm posting some to someone (Daza) on RCUK soon, so if you want some, I can post you some too.  :glad:

Seems crazy LFSs don't sell it, I've not seen it in any either, it'd grow rapidly in their nutrient rich systems and be a constant revenue source both through selling of the Chaeto itself, and through reduced water changes etc.

Mike does that bulb array have a bayonet fitting,  just getting round to sorting a light for the sump.

Neither are bayonet. They're both ES (Edison screw).

I had a real hard time finding ES fittings in B&Q and at Screwfix, so I got mine online.

If you can find the lamp in Bayonet, then LFMF and get that, as bayonet fittings are much more widespread in this country now than ES... :(

I also had a hard time finding a gooseneck extension for ES, but I've got one in the post now to lower the lamp about 6 inches closer to the water.

Make sure your lamp won't become submerged when the power cuts and the sump level rises, obvious, but bad news if it slips your mind...

Hadn't planned getting the lamp that close!
As for the light, I should be looking for 7w and above,

Mine will still be about 4 inches above the surface, or about 2 inches above the water level when the sump reaches full capacity.

Remember that lighting intensity follows the inverse square law, just like a camera flash, it's inversely proportional to the square of the distance.

So half the distance and you get 4 times the intensity. Double the distance you get 1/4 of the intensity.

That's my reasoning for moving it closer.

Yeah, I found them too, but I didn't want adaptors, etc, so just ordered the ES fittings on eBay, just means I'm stuck with that now.

I suppose a slight plus, is that with ES there's no chance of doing what you can do with Bayonet, where if you knock the bulb, it'll come pinging out of it's socket...

That 4.8w bulb in the 2700k would be good, but it's not that powerful only 4.8w... Also the SMDs look exposed on it, if they are, salt creep would quickly finish them off.

The bulb I've got, which is going to be replaced when I get home with the red/blue one, the LEDs are "CREE" style, and are covered by lenses.
