My Version Of Parabolic Spider Reflectors

[CalciumReef]

I made it at a much lower price than market is selling.

[Golden Tooth]

Wats the material used bro.?

[CalciumReef]

Its made of stainless steel...mirror finish...will be making two more to house my mh,2 saki and 2 radium.If anyone interested in it i can make at the same time.

[DaY]

how much for one of them?

[CalciumReef]

It can be made at $45 each if i get more support....

[hoppinghippos]

woah, nice reflector you have there!! Any reason why you chose SS instead of aluminium? And how did you bend the steel?

[CalciumReef]

Anymore members out there DIYing MH require this kind of reflector cos i will be consolidating the orders.Goldentooth has ordered one.

[SpiderOne]

erm. there is another reefer doing this also and ur product looks.. different from his. one of the main things about the effectiveness of spider reflectors is the precise angle they are bent at. urs looks a little too.. compact

[CalciumReef]

Spent a lot of time measuring and calculating the size and angle of my version of spiderlight reflectors.Photos are not necessarily accurate.Its up to you to decide.

[SpiderOne]

got pic of it in action?

[CalciumReef]

Not at the moment.Btw,the reflectors are not stretched open yet.Thats why it looks compact

[KingFish]

Hmmm ... that is one of the better bootlegs I've seen

I'm curious, how exactly did you calculate the angles? Simulations?

[CalciumReef]

I made a model of it using cardboard before making the actual thing.Calculated to scale of The ORIGINAL spiderlight.Just did some testing a moment ago,the angle of reflection is huge!

[orgasbt]

good idea. But how are you going to house the Bulb for SE or DE??

Dont quite get it. Pls explain how to fix the bulb it.

Thanks

[CalciumReef]

Just fix a mogul onto the reflector.The mogul will hold the E40

[robe]

Just take note that to get the refelctivity your bulb position must be exact (distance of the bulb center axis from the reflector top center axis as measured along its lenght) otherwise the parabolic effect will not be optimise and you have light scattering.

[CalciumReef]

Anyone else needs the reflectors?Will be making the rest of my reflectors at the end of this week.

[Achilles Tang]

I think you should stretch it out first.

To me it looks weird as the edges seem to be parallel to each other and causing light beams to bounce off each other and not back into the tank.

[reefer guy]

correct me if im wrong, but if calculations are made accurately, changing the angles or stretching it out would make the calculation useless. and as robe says, the position of the bulb mounted should be precise as well to get the desired reflection.... would like to see it in action soon, hope u can post a pic soon n i might consider getting one....

[altec]

hi seems like your angel of the bending is abit incorrect from the 2nd angle to the last bending and the finishing of the sides as i examine mine,the last bending of your is too much liao so the MH reflection angle will not cover every part of the tank.where else the rest of the it the angle is too small just my opinion to let you know.

[CalciumReef]

Will try to post a picture of it in action soon so that your can judge whether it works anot.Its not stretched open so the picture is inaccurate!

[SpiderOne]

anything in the basic shape will spread light.

[piero]

And one more thing answering one of the questions. Aluminium will give U a electric shock while SS wun... But its ex ah... Anyway I would like to see some pictures too... Great if it does works....

[CalciumReef]

Goldentooth has collected one of my reflector.Hope he can post a picture of the reflector in action soon.

[CalciumReef]
