Basic lamps have for a long time been constructed in such a way that they are interconnected. When the power comes from the source, it passes through wires also known as electrodes and on reaching the bulb, produces light. The newer versions of lights such as induction street lighting lamps are constructed with no direct connections. Basically no wires are passing the inside of the bulb since the power is transmitted through electromagnetic or radio waves.
Since electrodes are most susceptible to damage, without them the bulbs can last much longer. The light from electrode-less lamps does not flicker because they do not get affected by any form of vibration. In short, you can now get long lasting lighting solutions which you can rely on. Once this is in place, anyone with access can determine when to switch on and for how long through IP control giving you much more freedom.

I am shifting into an mature apartment and there are no ceiling lamps in the bed room and dwelling room. I bought a ground lamp from Walmart and 75W ‘daylight’ electricity saving bulb from Home Depot. I locate the lights dull and not very good enough to study with-I’m a student. This is truly bothering me, how ideal can I mild the rooms making use of lamps and have sufficient light in them? I want them well illuminated and never want to ruin my eyes either.
A circuit contains six 210 ohms lamps and a 8 ohms heater connected in parallel. The voltage across the circuit is 132 V. What is the current if six lamps and the heater are operating? Think about this situation with a 12 A fuse in the line. Answer in units of A.
also, where can i find them? my roommate and i are starting growing plants indoors and then we are putting them outside, im looking for the best growing lamps there are. i heard of a VHO lamp, but i have no idea what that is. please help!
I’m growing nothing that i couldn’t put outside for the rest of the world to see.

I have read that LED lamps reduce the consumption of electricity to a great extent. But are they connected to the circuit along with resistors? In such case how they reduce the consumption of electricity?
Also, if you do use different lamps do you use the same lamp shades?
I am moving into an older apartment and there are no ceiling lamps in the bedroom and living room. I bought a floor lamp from Walmart and 75W ‘daylight’ energy saving bulb from Home Depot. I find the lighting dull and not good enough to read with-I’m a student. This is really bothering me, how best can I light the rooms using lamps and have adequate light in them? I want them well illuminated and don’t want to ruin my eyes either.

Where can you get those kind of lamps??? Please help and put the link of the website. If it’s over 20 bucks we don’t want to hear about it!
When were the first street lamps used? I believe I have narrowed it down to the 19th century, but can anyone give me the actual year? Is there a picture anyone could provide?
I know that they can have various Wattage, practically from 5 to 40 Watts, 18W being equivalent to the old 60W.
They can have different color temperarture, 3000K being closer to the traditional incandescent bulbs and 5000K-7000K being significantly whiter.
Once, 8 years ago, I purchased few bulbs and they had this bad sideffect that they had some delay before turning on. This was something that people should know.
Today I see that prices online range from $3.50 to $30 a bulb.
What should I look for except for Watts/color temp?
Why some of them are so cheap? Any catch there?
How reliable they are? I barely used mine from 8 years ago and now they are dead for some reason.
Are there still bulbs around that have delay before turinig on?
In short, what should I know and look for buying them?
I just bought some fluorescent bulbs.
One more thing to know is that if you have the brightness control it isn’t going to work since it’s usually designed for the linear simple circuit only.
It’s interesting to know if this problem is solved/solvable in some way or not for fluorescent bulbs.

please paraphrase the expression ‘promise lighting’? does it say about prospectives in future development of lapms or what people could wait from such lamp?
it’s from here
Induction light bulb, promise lighting
Friday, 20 November 2009 19:41
Induction light bulb, promise lighting,electrodeless lamp, known as a radiofluorescent lamp or fluorescent induction lamp. induction bulbs, electrodeless light bulb These lamps have no wire conductors penetrating their envelopes, and instead excite mercury vapor using a radio-frequency oscillator.
I’ve been wearing a holter monitor for the past month and when I took the electrodes off and it left this black sticky residue on my skin. I’ve tried scrubbing it off in the shower, olive oil and rubbing alcohol and nothing seems to work. Does anyone else have any ideas on how to get this stuff off?!
