Honoson 20 Pcs Miniature Screw Tiny Light Bulbs Replacement E10, 3.8v, 0.3a

I needed these to replace a bulb in an old (1960s) slide viewer that still works perfectly. Some of the online speciality bulb stores wanted almost $10 to ship *one* bulb. These are very reasonably priced and do the job. Some reviews say that they burn out too quickly---I haven't experienced that yet. But at this price, I don't mind. I also liked the plastic storage case they were shipped in!

Got the bulbs works. They arrived on time. I used it for my musical bells. Would buy from this vendor again. They fit perfect.

Headline Description: "Honoson 20 Pieces Miniature Screw Tiny Light Bulbs Replacement E10 Mini Light Bulbs E10 Socket Miniature Flashlight for Physical Electrical Experiment Screw Base (3.8V, 0.3A)." A jumble of words in a semi-logical order - Key words: 20 Pieces, yes - E10 - yes, 3.8V, 0.3A assumed rating. Style: 3.8V, 0.3A Apparently using the designation "style" allows the seller to sell several versions or ratings considered to be one product. The reviews for all styles of a product are limped together. Brand Honoson - ok Light Type Incandescent - ok Special Feature Energy Efficient - compared to what? - nonsense Wattage 20 watts - Watt = volts x amps 3.8V X 0.3 A = 1.14 watts 20 watts is nonsense Bulb Base E10 - ok About This Item - more of the same with some nonsense added. Warning to use at 1.5 V - nonsense I tested one bulb at 4.03 volts, three AA cells in series. Measured current, 0.31 A. Calculated power. 1.25 watts. The base is marked 3.8V 0.3A The pictorial presentation mentions that the bases are "solid" aluminum,, whatever that means in this context. A quick examination and test of all 20 bulbs did not reveal any problems.

Good lamps

poor quality not good not bright it looks damn so sad

I purchased some antique Christmas light guts requiring this odd size bulb. Amazon never lets me down finding what I need.

Given as a gift for an older set of musical Christmas bells. My friend was so happy to get them and the set is working perfectly !

Review for Honoson 3.8V and 6V bulbs. These bulbs are at best an average value at around $0.30 each. They are fairly rough in fit and finish compared to a name brand bulb I have in inventory retailing for $0.95. But my name brand supplier ran out and isn't restocking. The days of the incandescent bulb of all sizes are numbered. So get some while you can. I received 20 bulbs in a plastic box. I like that because it's small enough not to clutter the shop but large enough not to get lost. One of the 3.8V bulbs was DOA with no obvious reason. The filament looks whole so the base leads must be at fault. All 6V bulbs worked as expected. 8 of the 3.8V bulbs have wildly off-center filaments (see photo) that will be very noticeable depending on your application. 3 of the 6V bulbs also have way off-center filaments. 11 of the 3.8V bulbs look good with bright, centered filaments. 17 of the 6V bulbs look good but remember that the illumination is the same for 6V and 3.8V. You won't get twice the illumination. The 6V bulbs are not as efficient as the 3.8V bulbs. At 3.8V the current drawn varied between 250mA and 280mA which is close enough to the rated 300mA but is still a large variation. For the 6V bulbs the current draw was pretty consistent at 470mA. Brightness varied noticeably between bulbs but not enough to be a concern for my application. Each of the 3.8V bulbs I received had a concerning green residue on the base (see photo) that looked a lot like copper corrosion. I was able to remove the green residue with a rag and 99% alcohol. Under close inspection the green residue appears to be leftover adhesive from when the bulb was glued to the base (see photo). The soldering on the base and center conductor are very rough with a lot of variation between bulbs and several with incomplete coverage. Overall these bulbs are an average value for the price. Get some while they are around for your vintage toys and games. It is unlikely that an LED will have equivalent color or spread of illumination that these incandescent do and won't look right. Some electronic circuits depend on the negative resistance response of an incandescent bulb and won't work with an LED. Get some before they are outlawed. Also: I wish I could have written a separate review for the Honoson 1.5V bulbs. These are a great value. All the 1.5V bulbs I received had centered filaments, bright and well finished bases, good solder joints, and very consistent brightness and current draw of 280mA. These were a very good deal.
