Fluorescent tube bulb with internal reflector, where can I get this?

[SpatiallyAware]

You might want to take a look at indoor tomato grow lights, they're common in T5 configurations.

I see it's the first for many people who have not heard of the OP.

To do the favor inextricably explaining why fleabag (OP) is doing this, has to do with a fact s/he is an hypothetical energy-saving conversationalist to the extreme. There are past examples of (impractically) proposed energy savings schemes that still remain unsolved for the most part. The latter having been derailed for some.

We all need to get our first epic thread posts in some time.

The similarities between fleabag and Jerboy grow by the day.

With the millions (billions?) of these bulbs in use you ARE NOT coming up with a new idea a hundred different engineers didn't already think of.

Of course not! That's why I linked to the wikipedia article instead of behaving like as if I came up with a new idea! My point was, I wanted to buy this thing they described in the article, not create it myself which while I could, I'd rather not.

There are plenty of retrofit lighting kits out there for aquarium use. The reflectors on these are mirror like but curve tightly around each bulb to direct most of the light straight down. If you were to hang these in a room it'll just be a bright spotlight underneath the fixture.

To light up a room it'll be better to get something like a florescent shop light that throws more of the light around the room.

Unless you are fitting out a grow room this whole exercise is pointless. You might as well inflate your tires to sidewall just to save more gas, and who in their right mind would waste time and safety doing that?

But inflating tires to sidewall is worth it and is a substantial savings. In a sense, you've said that what I'm saying actually makes sense, therefore you're wrong and I'm right, that not only inflating to sidewall makes economic sense but using a reflector does as well.

My school uses these bulbs in all there housings. That usually hold 3. Light output is fine.

Painting the lamp on the outside will reduce output not make it more directional. At one time standard (t12) bipin fluorescent lamps could be purchased with an internal reflector and only emitted light from one side but they don't make those any more IIRC.

Aluminized mylar is highly reflective and safe and can be mounted behind a tube to increase luminous intensity immediately below it.

I was also thinking of doing this. Are you saying I should wrap the mylar around the lamp or should I mount it on the fixture itself?

If you wrap the tube it will reduce output. You need to experiment with parabolas to see what gives the most desired mix of cut off and lux.

 

[squirrel dog]

double sided tape and aluminum foil on the fixture should get your reflection in the right direction if you get my inflection.

Light is of no use to you unless it enters your pupils and is detected at the back of your eyeballs. You are wasting over 99% of your room light with it being absorbed by various surfaces and never reaching your eyes.

I recommend just taping tiny LEDs to your corneas and putting a reflector behind them. You should be able to ensure the vast majority of photons enter your eyes where they are useful this way, resulting in maximum efficiency for almost no cost.

Tritiated aerogels would be superior in this instance since they are self contained/self powering and have outstanding lumen maintenance over a two decade period!
